There has been an abundance of new information in the media over the past few years about autoimmune disorders. Essentially, an autoimmune disease is a condition where your immune system mistakenly attacks your body. When our bodies identify foreign invaders (viruses, bacteria, etc.), it sends out specific cells to attack these intruders. This is our body’s way of working to rid itself of agents that are attempting to make it sick. With an autoimmune disease, the immune system mistakes part of the body as foreign. It could be your skin, joints, or other part of your body. As a result of this confusion, these healthy cells are attacked by proteins called autoantibodies.
Why Does This Happen?
It’s still unknown why the immune system gets confused, but there is evidence that some people are more likely to have an autoimmune disorder than others. Women are more likely than men to develop this type of disorder and certain ethnic groups are more likely to have particular autoimmune diseases.
The incidence of autoimmune diseases is rising, causing many experts to analyze environmental factors such as diet, infection, and exposure to certain chemicals as potential culprits.
Common Autoimmune Diseases
So far, doctors have identified and categorized more than 80 autoimmune diseases. Some of the most common ones include:
Many autoimmune diseases present similar symptoms in the early stages. Here are a few things to look for:
Depending on which autoimmune disease is present, there may be more specific symptoms. Some disorders can come and go over time. A flare-up is a period where symptoms are present versus a period of remission where the symptoms are dormant. In any situation, if you are concerned, speak with your doctor. There are tests available that can determine if you do have such a condition, although, without further testing and research, it can be challenging to know for sure which one. Doctors use your symptoms and additional tests to confirm a diagnosis and begin a treatment plan.
Your Immune System & Aging
The aging of the immune system is called “immunosenescence.” A decrease in our immune system’s power occurs naturally as we age. It can become slower to respond, which can increase your risk of becoming ill. Vaccines and flu shots may not be as effective or last as long due to this decrease in the immune system’s ability. Additionally, there are fewer cells present in the immune system to conduct healing, so an elderly person’s body may heal more slowly. There is an increased prevalence of autoimmunity and autoantibodies as we age. Older adults are more susceptible to viral and bacterial infections. Cancer risks are increased because the body’s ability to detect and correct defects are not as strong.
Keep Your Immune System Strong
To keep your immune system healthy, there are several things you can do. These should become life-long habits that keep you healthy long-term and not just when you might be feeling ill:
