Polymyalgia Rheumatica – Potential Causes and Triggers

Polymyalgia rheumatica, or PMR, is a chronic inflammatory disease that affects the major muscle groups of the body. The hip area, neck, and shoulders are some of the most affected regions. PMR is one of the most common rheumatic conditions in the demographic of people over 50 years old. The condition is also relatively more prevalent in females than in males. Despite its prevalence, the condition is difficult to diagnose and treat since no specific tests or definite causes exist.

Polymyalgia Rheumatica – Potential Causes and Triggers

Genetic predisposition
Genetic factors are one of the common causes of polymyalgia rheumatica. The condition may affect individuals who have a family history of the condition or a related autoimmune condition. Therefore, PMR may also affect individuals prone to giant cell arthritis or rheumatoid arthritis. There is still some ongoing research to help find the genetic markers that make individuals more susceptible to PMR.

Immune system dysfunction
Another factor that can play a functional role in the pathogenesis of PMR is the immune system. When the system shows signs of dysfunction, it can attack the healthy cells in the body and result in increased inflammation and pain. It can make things more difficult for the patient by triggering the affected areas. Although, it has not yet been determined what exactly triggers this malfunction of the immune system. Bacterial and viral infections are some possible triggers.

Inflammatory response to infections
As discussed above, some viral and bacterial infections are suspected to cause PMR. Certain microbes that impact the respiratory system can also be regarded as potential causative agents for polymyalgia rheumatica. Theoretically, it is believed that the immune system responds to these infections in the body, and the process leads to increased inflammation. This attack by the immune system can also make the affected individuals more susceptible to the occurrence of PMR. However, like other possible causes, more research and proof are needed to establish a proper link between some pathogens and their role in PRM onset.

Environmental factors
Another possible cause of polymyalgia rheumatica is the environmental factors surrounding the individual.   Many people are exposed to a wide variety of toxins and pollutants in their daily lives. These chemicals can play a role in the development of PMR. In some cases, they might even exacerbate other conditions that can fast-track the process of onset. It is believed that environmental factors can also interact with the genetic traits that make individuals more susceptible to the condition. They can also enhance the immune system dysfunction, perpetuating the inflammatory process and aggravating the pain in affected tissues.

Age and hormonal changes
The age group of 50 years and above is the primary demographic of PMR. The most documented cases of the condition are in people who have reached or crossed 70 years. This indicates that age-related changes in an individual’s hormonal levels and immune system can act as a contributing factor. Hormonal fluctuations can send the immune system into a tizzy and might affect the patient’s ability to fight off the condition’s onset. In particular, the fluctuations in the levels of the hormone cortisol have been found to significantly impact the disease’s pathogenesis.

Autoimmune mechanisms
PMR is often considered an autoimmune condition where the body’s immune system mistakes healthy cells and tissues for foreign entrants and starts attacking them. As suggested earlier, due to a lack of concrete research, it is hypothesized that a faulty autoimmune mechanism could also contribute as a causative factor in PMR onset. The process is believed to be driven by immune cells, signaling pathways, and the inflammatory cytokines responsible for the body’s inflammatory response. However, the specific triggers that initiate and perpetuate these autoimmune mechanisms remain the subject of ongoing research.

It is difficult to comment on or pinpoint what caused a particular PMR onset as the causes remain elusive. However, the possible reasons are believed to be a complex involvement of autoimmune malfunction, genetic predisposition, aging, environment, and fluctuating hormones. It is, therefore, important to pay special attention to possible causes and triggers to provide proper treatment and management options to the patients. These options can help improve the patient’s quality of life and help maintain their active daily routine.

Stress
Patients often ask, can stress trigger polymyalgia rheumatica? And the simple answer is yes. Psychological stressors that affect the person’s physical and emotional state can act as active sources that exacerbate their symptoms. Stress has also been known to increase the inflammation in the body and subsequently worsen the patient’s pain, fatigue, and stiffness. PMR patients are often advised to adopt stress management techniques, including mindful breathing practices, relaxation, low-impact exercises, indulging in hobbies, and spending time in nature.

Infections
Infections are another potential trigger that can make things difficult for PMR patients. However, the exact mechanism of how it affects the patient is yet to be determined. It is believed that when patients contract specific viral or bacterial infections, their immune response is triggered. The immune system then activates an inflammatory response in an attempt to deal with the pathogen and infected cells. However, since the patients of PMR are already dealing with high inflammation, the immune response against the infections can aggravate their existing symptoms. Some might experience frequent flare-ups when dealing with an infection.

Treatment
Some treatments that affect the immune system of individuals might also act as a trigger for PMR patients. If a patient is receiving treatment for an underlying autoimmune condition or any immunity-altering treatment, they need to be closely monitored for any sign of PMR. Close monitoring of side effects and symptoms is essential for accurate diagnosis and management of PMR.

An Overview Of Colon Polyps

An Overview Of Colon Polyps

An overview of colon polyps Colon polyps are small clumps of cells formed on the lining of the colon. The majority of these polyps tend to be harmless, but with time, there are certain polyps that can easily grow into colon cancer. This is a serious condition, especially when found in the later stages. Almost any individual can develop colon polyps. People who are over 50 years of age are at an increased risk of suffering from this condition. Even smokers and overweight individuals or people with a family or personal history of colon polyps might be at an increased risk of suffering from this condition. Colon polyps – causes are slightly known, but this condition rarely causes any symptoms. Therefore, for individuals who are at risk of developing the condition, it is important to have screening tests on a regular basis. These will include a colonoscopy. Polyps found in the early stages can conveniently be removed. They can be removed completely in a very safe manner. Regular screening is the best step for the prevention of colon polyps. What are the colon polyps – causes? Doctors do not exactly know the causes of colon polyps, but they are of the view that polyps are a result of abnormal tissue growth. The human body develops healthy cells in a periodic manner, thus replacing the old cells that tend to be damaged or are no longer required. The division and growth of these new cells is regulated. However, there are cases when the new cells develop and then divide before they are actually needed. It is this excessive growth that results in polyps. Packaged red meat is also one of the most common colon polyps – causes. Fiber deficiency in the body. High-fat diet taken in excessive amounts. Smoking cigarettes. Obesity is also one of the major colon polyps – causes. Inherited conditions such as Gardener syndrome, familial adenomatous polyposis, and Peutz-Jeghers syndrome might also put an individual at an increased risk of having colon polyps. What signs and symptoms do colon polyps show? Majority of the individuals suffering from colon polyps do not show any symptoms. They are actually unaware of the fact that they have polyps, because they feel very well. Bleeding from the rectum is one of the most common symptoms of colon polyps. Blood in the stool can also be a sign of colon polyps. Blood might make stool look black, or there can be red streaks in stool. A feeling of tiredness due to anemia and not having sufficient iron in the body are common symptoms. It is the bleeding from the polyps that can result in an iron deficiency and anemia. Several other health issues might also result in these signs. Nevertheless, if rectum bleeding or blood in the stool are everyday phenomena, a consultation with a doctor is vital. How can colon polyps be prevented? Knowing the colon polyps – causes can help prevent the condition. However, there are other important steps that can be followed in trying to prevent this condition. They are as listed: Regular screenings. Lifestyle changes can also be of help in doing away with the colon polyps – causes, and, consequently, prevent them. Adopting healthy habits such as eating fruits, whole grains, and vegetables and reducing fat intake can help in the prevention of colon polyps. Limiting the intake of alcohol and quitting tobacco. Staying active physically and maintaining a healthy body weight is also important. When should one see a doctor? A general physician must be consulted in case of the following: Blood in the stool Abdominal pain Changes in bowel habits for more than a week It is important for one to have a word with their physician regarding their intake of vitamin D and calcium. This is because studies have proved that increasing the intake of food items rich in vitamin D and calcium can help prevent the recurrence of polyps. However, this is not completely clear. It is important to consider all the options, especially if one is at a very high risk of suffering from colon polyps.

The Types Of Colon Polyps And Their Prevention

The Types Of Colon Polyps And Their Prevention

The types of colon polyps and their prevention Growths that occur on the inner lining of the colon (large intestine) and usually protrude into the colon are known as colon polyps. They form when the genetic material within the cells that line the colon changes and becomes abnormal. Under normal circumstances, the immature cells that line the colon multiply, mature, and then die in a timely fashion. On the other hand, the genetic changes in the lining cells prevent the cells from maturing, and they don’t die. Resultantly, immature and genetically abnormal cells start accumulating in the colon, eventually resulting in the formation of polyps. This article intends to raise awareness about colon polyps, its types, symptoms, diagnosis, the colon polyps – causes, and more. What are the types of colon polyps? Inflammatory colon polyps : Also known as false polyps, it is mostly found in people who have inflammatory bowel diseases (IBD), such as Crohn’s disease or ulcerative colitis. These polyps are inflammatory manifestations of IBD, are benign, and are unlikely to become cancerous. Adenomatous colon polyps : Also known as adenomas, this type of colon polyps make up about 70% of all polyps found in the colon. They can become cancerous, but the process takes years. Hyperplastic colon polyps : The term hyperplasia means fast growth, which indicates an abnormal increase in the number of cells resulting in the gross enlargement of the colon polyp. Despite the rapid growth, hyperplastic polyps have a low risk of turning cancerous. Villous adenoma : This type of colon polyp has a greater potential of becoming cancerous. It is estimated that approximately 30 percent of villous adenomas develop into a malignancy. These polyps require surgery for the removal of their cauliflower-like protrusions. What are the causes of colon polyps? Experts are not sure about the colon polyps – causes. However, the causes are believed to be a mix of environmental and genetic factors that result in an abnormal tissue growth. What are the known risk factors of colon polyps? Age : The risk of developing colon polyps tends to increase with age. Family history : A close relative with colon cancer or polyps raises the risk. Sex : Men have a slightly higher chance of developing polyps. Race : Black men and women have a higher risk. Alcohol : Alcohol consumption is closely linked to colon cancer risk and is known as one of the colon polyps – causes. Red meat : If not had in moderation, red meat can serve as one of the colon polyps – causes. Having too much red meat increases the risk of colorectal cancer as well. Lack of dietary fiber : A good intake of fiber has many benefits, including colon benefits. It decreases the risk of colon cancer. Smoking : Smoking increases the risk of all types of cancers, and colon polyps or cancer is no exception. Obesity : Obese people are at higher risk of developing colon polyps and cancer. How are colonic polyps diagnosed? The following tests help diagnose colon polyps: Colonoscopy Sigmoidoscopy Barium enema CT colonography Stool test What are the symptoms of colon polyps? Change in stool color Rectal bleeding Iron deficiency Anemia Change in bowel habits Abdominal pain Blood in the stool Fatigue How common are colon polyps? They are very common. They increase in prevalence as people age. If one has colon polyps, they are more likely to develop polyps elsewhere in the colon later. Only a small proportion of polyps cause symptoms or signs, which usually are the result of bleeding from the polyp. How can colon polyps be prevented? Adopt healthy habits : Adopt healthy habits and increase the intake of fruits, vegetables, and whole grains. Limit fat intake, alcohol consumption, and quit tobacco. Stay physically active and maintain a healthy weight. Avoid all the estimated colon polyps – causes. Seek advice if at high risk : If there’s a family history of colon polyps or its other risk factors affect one, seeking prompt medical advice and counseling is important. With regular colonoscopies, one can prevent the colon polyps – causes from developing, and hence preventing the colon from developing.

Carcinoid Neuroendocrine Tumors – Prognosis And Life Expectancy

Carcinoid Neuroendocrine Tumors – Prognosis And Life Expectancy

Carcinoid neuroendocrine tumors – Prognosis and life expectancy The neuroendocrine system is a complex regulatory mechanism comprised of cells spread throughout several organ systems, including our lungs and digestive system. As they have characteristics of both nerves and endocrine cells, they are called neuroendocrine cells. The nerve cells transmit signals using electrical impulses, whereas endocrine cells make thyroid and insulin-secreting glands. This article intends to discuss the carcinoid neuroendocrine tumor that starts in these cells in detail. What is a carcinoid neuroendocrine tumor? A carcinoid neuroendocrine tumor starts in the cells of the hormone-producing organs in our body. A carcinoid tumor is a type of neuroendocrine tumor that most commonly arises in the gastrointestinal system, which includes intestines, stomach, and esophagus. Carcinoid tumors account for about 1% to 2% of lung cancers. As carcinoid tumors originate from tissue that produces hormones, the main side effect of the condition is the inappropriate release of various hormones in the bloodstream. Carcinoid neuroendocrine tumor can arise in a number of locations categorized into three areas: the foregut, midgut, and hindgut. Lungs and stomach form the foregut area. The midgut comprises of the small intestine, colon, and appendix. The hindgut includes the end of the large bowel, the rectum, and genitourinary tract organs (ovaries and testes). What factors raise a person’s risk of developing a carcinoid tumor? A family history of multiple endocrine neoplasia type 1 : This hereditary condition increases an individual’s risk of developing tumors in the pituitary gland, pancreas, and parathyroid gland. Age : Age seems to be a major factor that plays an integral role, as children rarely develop carcinoid tumors; the average diagnosis age is 55 to 65 years for this condition. Race and gender : Carcinoid tumors are more common among black people than white people, and black men have a higher risk than black women. White men and women have the same risk levels, and after treatment, women tend to live longer. Other medical conditions : Some medical conditions that damage the stomach and reduce acid production increase the risk of developing a carcinoid neuroendocrine tumor. What are the symptoms of a carcinoid tumor? Signs and symptoms of a carcinoid neuroendocrine tumor depend on where the tumor develops: Carcinoid tumors in the lungs : The symptoms of a tumor in the lungs are chest pain, wheezing, diarrhea, shortness of breath, skin flushing (redness and a feeling of warmth on the face and neck), weight gain, particularly around the midsection and back, and pink or purple marks on the skin, which look like stretch marks. Carcinoid tumors in the digestive tract : The symptoms, in this case, are abdominal pain, diarrhea, nausea and vomiting, intestinal blockage, causing an inability to pass stool, rectal bleeding and pain, and skin flushing. What are some effective management tips for the symptoms of carcinoid neuroendocrine tumors? Facial flushing : Avoid stress and ask your doctor about specific foods that cause facial flushing so that you can avoid them. Diarrhea : Ask your doctor for anti-diarrheal medication. Wheezing : Ask for medication that relaxes muscles in the lungs to make breathing easier. Heart problems : Discuss your heart issues with your doctor so that they can prescribe diuretics, which lower the blood pressure. Carcinoid syndrome : Use octreotide on prescription, which is the most effective medication to treat carcinoid syndrome. What is the prognosis for carcinoid neuroendocrine tumor? Carcinoid neuroendocrine tumors can be benign (non-cancerous) or malignant (cancerous). Benign carcinoid tumors are small and can be removed completely. They don’t come back and don’t spread to other parts of the body. They don’t produce any symptoms as well. Malignant carcinoid tumors are large, and their cells can invade and damage the surrounding tissues and organs. Additionally, malignant cells can enter the bloodstream or lymphatic system and can even form new tumors in other parts of the body. Lymph nodes, lungs, bone liver, and skin are the common sites for carcinoid metastases. Carcinoid tumors grow slowly in comparison to other cancers, such as lung, colon, pancreas, or liver cancer. Patients with larger malignant carcinoid tumors (with or without metastasis) can survive and have a good quality of life after proper treatment. Adenocarcinoids, a rare form of carcinoid tumors, are more aggressive than the typical malignant carcinoid tumors.

What Are The First Signs Of Liver Damage

What Are The First Signs Of Liver Damage

Liver damage – What are the first signs? On the right side of the abdomen, below your rib cage, is an organ called the liver. It is the size of a football and is one of the most important organs in the human body. The liver aids in the digestion of the food we eat and also helps in flushing out the toxins from our body. When there is any kind of disturbance in the normal liver functioning, then it can cause a significant damage to the human body. Once you start exhibiting the signs of liver damage, it is important to get the exact diagnosis and take the next steps accordingly. What are the causes of liver damage? There can be a number of causes for liver damage: Liver infection is one of the most common causes of liver damage. Viruses and parasites can cause infections that affect the normal functioning of the liver. Hepatitis is the most common liver infection, which includes Hepatitis A, Hepatitis B, and Hepatitis C. Some diseases will affect your immune system thereby damaging your liver too. This is called autoimmune hepatitis. Primary Sclerosing Cholangitis and Primary Biliary Cirrhosis are of the same kind. If you have inherited an abnormal gene from any of your parents or family members, it can lead to a build up of various substances in the body and hence can damage the liver. Build up of liver cancer can be a cause. A person who is an alcohol addict is more prone to liver damage. What are the first signs of liver damage? There can be several signs of a liver damage. Here are 10 signs of liver damage that you need to pay attention to: Your eyes and skin turning yellow, which is usually a sign of jaundice. Abdominal swelling and pain are also symptoms of liver damage that you should watch out. Your ankles and legs begin to swell.. Your urine becomes dark yellow in color. There can be many reasons for dark yellow urine, but it can also be a sign of liver damage. Excessively itchy skin is also a symptom of liver damage. Loss of appetite. Getting bruises easily as your liver fails to create proteins needed for blood clotting. Vomiting and nausea for no reason. Blood in the stool or pale stool. Chronic fatigue. How is liver damage diagnosed? In order to get started with the liver damage treatment, it is very important to diagnose the symptoms of liver damage correctly. In order to start the diagnoses, your doctor will start with a physical examination, followed by requesting details of your health history. Liver function tests, which are blood tests will be done at the initial stage. MRI Scan and CT scan kind of image tests are done. Tissue analysis is also done to get an accurate idea of the problem . How is liver damage treated? The treatment for the liver damage depends on the type and severity of damage. Some stages can be treated with just slight modifications to the diet and lifestyle like weight reduction, no smoking or alcohol. Further stages will require medication and severe condition will need a surgery. If your liver has failed completely, then you will have to go for a liver transplant, which is an expensive and time consuming process. How can liver damage be prevented? Certain changes in your lifestyle can prevent liver damage. You need to stop drinking alcohol or only drink a moderate amount to decrease pressure on your liver. Get vaccinated to prevent getting hepatitis infections. When you are spraying insecticides or other aerosol sprays, make sure that you cover your nose and also make sure to protect your skin. You need to maintain a healthy weight as there are chances of fatty liver damage as well. You should take only medicine that is prescribed to you and make sure that you do not take any medicine in excess or without talking to your doctor.
