Autoimmune Diseases: Types, Symptoms, Causes, Diagnosis & More

An autoimmune disease is a condition in which your immune system mistakenly attacks your body. The immune system normally guards against germs like bacteria and viruses. When it senses these foreign invaders, it sends out an army of fighter cells to attack them. Normally, the immune system can tell the difference between foreign cells and your own cells. In an autoimmune disease, the immune system mistakes part of your body, like your joints or skin, as foreign. Some autoimmune diseases target only one organ. Doctors don’t know exactly what causes the immune-system misfire. According to a 2014 study, women get autoimmune diseases at a rate of about 2 to 1 compared to men — 6.4 percent of women vs. 2.7 percent of men.

Some autoimmune diseases are more common in certain ethnic groups. Certain autoimmune diseases, like multiple sclerosis and lupus, run in families. A “Western diet” is another suspected risk factor for developing an autoimmune disease. 1. 2. 3. Effects of Hormone Therapy on the Immune Systems of Postmenopausal Women With Chronic Infections.

Adam Persky, Andrew Doyle, Chris Martens, Dennis Ryan Introduction The medical world has made great advances in treatments relating from high blood pressure to HIV and cancer.

The effect of exercise on immune function

One of the most common recommendations in most types of follow up treatments is to maintain a high quality diet and participate in an excise program on a regular basis. These suggestions are made because exercise has been proven to decrease LDL cholesterol levels while increasing HDL levels. In addition, exercise is known to decrease blood pressure and provoke a general overall feeling of contentment and well being. How does exercise affect leukocyte populations and/or activity? When dealing with endurance exercise there are generally three levels of exercise intensity: low, moderate, and high. How does moderate and high intensity bouts effects neutrophils (PMN)? Neutrophil counts are higher in athletes but the activity of the neutrophils are diminished (10).

Conclusion References. Overtraining effects on immunity and performance. Immunology and Cell Biology (2000) 78, 502–509; doi:10.1111/j.1440-1711.2000.t01-7-.x Top of page Introduction Overtraining is a process of excessive exercise training that may, if left unchecked, lead to a condition termed 'overtraining syndrome'.

Overtraining effects on immunity and performance

Overtraining syndrome is characterized by persistent fatigue, poor performance in sport despite continued training, changes in mood state and neuroendocrine factors and frequent illness, such as upper respiratory tract infection (URTI).1, 2 Overtraining syndrome reflects the body's inability to adapt to cumulative fatigue resulting from daily, intense exercise training that is not balanced with appropriate and sufficient rest. Athlete's guide to the immune system.

Something has gone wrong.

Athlete's guide to the immune system

Lately it seems that you have been sick a lot. You feel listless at home, bored at work, and your workouts have been lousy. Getting motivated for anything takes supreme willpower. When yet another upper respiratory infection hits, you decide to lay off the exercise and stew in the juices of frustration. What has happened? If this scenario sounds familiar the you're not alone. An opposing perspective comes from athletes, most of whom believe that they are healthier since starting an exercise program. The goal of this article is to review the current understanding of the athlete's immune system, and hopefully, teach you how to use this knowledge to stay healthy. What is the immune system? The immune system is a complex, dynamic, and beautifully orchestrated mechanism with enormous responsibility.

Training the immune system -- the "J" curve On the other hand, too much exercise can lead to a dramatically increased risk of URIs. Stress is cumulative. Chronic stress puts your health at risk - Mayo Clinic. Chronic stress puts your health at risk Chronic stress can wreak havoc on your mind and body.

Take steps to control your stress. By Mayo Clinic Staff Your body is hard-wired to react to stress in ways meant to protect you against threats from predators and other aggressors. Such threats are rare today, but that doesn't mean that life is free of stress. On the contrary, you undoubtedly face multiple demands each day, such as taking on a huge workload, paying the bills and taking care of your family. Understanding the natural stress response.

An interconnection between the nervous and immune system: Neuroendocrine reflex triggers infections. A newly-discovered reflex arc mediates a process which leads to a disruption in the hormones secreted by the adrenal glands which, in turn, results in an increased susceptibility to bacterial infections.

An interconnection between the nervous and immune system: Neuroendocrine reflex triggers infections

This research breaks new ground in the development of treatments to reduce the incidence of infections, and its results have been published in the current issue of Nature Neuroscience. Injuries to the brain or spinal cord, such as those caused by stroke or trauma, result in a considerable weakening of the immune system. This often leads to severe infections, such as pneumonia or urinary tract infections, which hamper nervous tissue regeneration as well as rehabilitation in affected patients. Until now, our understanding of the exact manner in which nerve tissue damage leads to infections (and which physiological parameters are responsible) has remained rudimentary at best.
