Your immune system is your body’s resistance to infections and other harmful invaders. Without it, you would always get immune system diseases, sick from bacteria or viruses. Your immune system is made up of individual cells, tissues, and organs that work together to preserve you.
The lymph or lymphatic, system is a significant part of the immune system. It’s a chain of lymph nodes and vessels. Lymphatic vessels are tiny tubes that branch, like blood vessels, throughout the body. They carry a clear fluid called lymph.
Lymph includes tissue fluid, waste products, and immune system cells. Lymph nodes are tiny, bean-shaped clumps of immune system cells that are connected by lymphatic vessels. They include white blood cells that catch viruses, bacteria, and different invaders, including cancer cells.
White blood cells are the cells of the immune system. They are made in one of your lymph organs, the bone marrow. Other lymph organs involve the spleen and thymus.
In overall healthy immune system plays an essential role to combat diseases.
What Happens When Your Immune System Gets Weak?
Below are the few weak immunity health problems.
Rheumatoid arthritis is an autoimmune disease in which the body’s immune system – which usually protects its health by invading foreign matters like bacteria and viruses – inadvisedly attacks the joints.
This provides inflammation that causes the tissue that lines the inside of joints (the synovium) to thicken, finishing in swelling and pain in and throughout the joints. The synovium makes a fluid that lubricates joints and encourages them to move smoothly.
Rheumatoid arthritis most generally affects the joints of the hands, feet, elbows, knees, wrists, and ankles. The joint effect is normally symmetrical.
That means if one knee or hand is affected, frequently the other one is, too. Because RA also can influence body systems, such as the cardiovascular or respiratory systems, it is called a systemic disease. Systemic means “entire body.”
Systemic Lupus Erythematosus
Systemic lupus erythematosus (SLE or lupus) is a condition in which the immune system is overactive and does not function correctly. The immune system attacks the body and generates inflammation in the skin, lungs, joints, kidneys, nervous system, and other organs of the body.
People who are with lupus can have times of very active condition, called a flare, and times where the disease is mostly quiet, called remission.
Nearly 20 percent of people with lupus caught the disease before 20 years of age. It is rare to notice lupus before age 5 years. Lupus is more obvious in females and particular ethnic groups, including African-American, Hispanic, South and Southeast Asian and North American First Nations populations.
Inflammatory Bowel Disease
The phase inflammatory bowel disease (IBD) represents a group of diseases in which the intestines become infected.
It has often been thought of as an autoimmune disorder, but the study suggests that chronic inflammation disorder may not be due to the immune system hitting the body itself. Instead, it is a result of the immune system attacking a safe virus, bacteria, or food in the gut, causing inflammation that leads to bowel injury.
Two main types of IBD are ulcerative colitis and Crohn’s disease. Ulcerative colitis is restricted to the colon or large intestine. Crohn’s syndrome, on the other hand, can affect any part of the gastrointestinal tract from the mouth to the anus. Most generally, though, it affects the last part of the small intestine or the colon or both.
If you have an IBD, you know it regularly runs a waxing and waning course. When there is critical inflammation, the disease is estimated active, and the person experiences a flare-up of signs. When there is less or no swelling, the person usually is without symptoms, and the condition is said to be in remission.
Multiple sclerosis, or MS, is a long-lasting condition that can harm your brain, spinal cord, and the optic nerves in your eyes. It can cause difficulties with vision, balance, muscle control, and other basic body purposes.
In MS, the weak immune system leads to shielding sheath (myelin) that incorporates nerve fibres and causes communication difficulties within your brain and the balance of your body. Ultimately, the condition can cause the nerves themselves to deteriorate or become permanently disabled.
The effects are often complicated for everyone who has the disease. Some people have mild symptoms and don’t require treatment. Others will have trouble getting throughout and doing everyday tasks.
Diabetes mellitus (or diabetes) is a constant, lifelong situation that affects your body’s capacity to use the energy found in food. There are three principal types of diabetes: type 1 diabetes, type 2 diabetes, and also gestational diabetes.
All types of diabetes mellitus have something in general. Usually, your body cuts down the sugars and carbohydrates you consume into a unique sugar called glucose.
Glucose fuels the cells in your body. But the cells require insulin, a hormone, in your bloodstream to take in the glucose and use it for energy. With diabetes mellitus, unless your body doesn’t make sufficient insulin, it can’t use the insulin it does produce, or a mixture of both.
Since the cells can’t take in the glucose, it makes up in your blood. High levels of blood glucose can injure the tiny blood vessels in your kidneys, heart, eyes, or nervous system.
That’s why diabetes — mainly if left untreated — can eventually cause heart attack, stroke, kidney infection, blindness, and nerve damage to nerves in the feet.
Chronic Inflammatory Demyelinating Polyneuropathy
Chronic demyelinating polyneuropathy (CIDP) is a neurological dysfunction that causes nerve swelling or inflammation. This inflammation damages the protective coating that is wrapped nearby nerves and fibres. Myelin is the name of this fatty layer.
As the myelin is destroyed, CIDP begins to symptoms such as tingling feelings in your feet and hands, as well as loss of muscle power.
CIDP is a type of received immune-mediated inflammatory disease. It isn’t deadly, but it’s chronic. In other words, the condition is long-term, and once you improve it, you’ll likely live with signs and complications of the disorder for the remainder of your life.
CIDP, like the other inflammatory diseases that are similar to it, engages your peripheral nervous system. This involves the nerves outside your brain and spinal cord. Understanding the various symptoms of each disease and how they can assist you, and your doctor concludes which is affecting your body.
Psoriasis is a noncontagious, chronic skin situation that presents plaques of hardened, scaly skin. The dry flakes of silvery-white skin scales result from the extremely rapid proliferation of skin cells. Psoriasis is an immune system problem.
The reproduction of skin cells is triggered by inflammatory chemicals offered by specialized white blood cells called T-cells. Psoriasis normally affects the skin of the elbows, knees, and scalp.
The spectrum of this autoimmune disorder ranges from mild with limited involvement of small areas of skin to difficult psoriasis with large, thick plaques to red inflamed skin concerning the whole body surface.
Psoriasis is contemplated a serious, long-term (chronic) inflammatory skin condition. It has a changeable course, periodically increasing and worsening. It is not uncommon for psoriasis to immediately clear for years and stay in remission. Many people note a worsening of their signs in the colder winter months.
Graves’ disease is an autoimmune disease. It causes your thyroid gland to generate too much thyroid hormone in the body. This situation is recognized as hyperthyroidism. Graves’ illness is one of the most popular forms of hyperthyroidism.
In Graves’ disease, your immune system produces antibodies known as thyroid-stimulating immunoglobulins. These antibodies then attach to healthy thyroid cells. They can cause your thyroid to produce too much thyroid hormone.
Thyroid hormones influence many aspects of your body. These can involve your nervous system function, brain development, body temperature, and other essential elements.
If left untreated, hyperthyroidism may cause weight loss, sensitive liability (uncontrollable crying, laughing, or other emotional displays), depression, and mental or physical fatigue.
Hashimoto’s thyroiditis is an autoimmune disorder of the thyroid gland. In autoimmune disorders, your immune system turns on your organs, cells or tissues that it is supposed to protect. The causes of common autoimmune diseases are not well understood.
Antibodies produced by the immune system illness the thyroid gland, slowly killing the cells that produce thyroid hormone. Low levels of thyroid hormone increase (hypothyroidism), regularly over months to years. Symptoms include fatigue, constipation, weight gain, depression, dry skin, and sensitivity to cold. Taking a daily oral synthetic thyroid hormone pill alters normal body functions.
Vasculitis is an autoimmune disorder in which the body wrongly sees blood vessels as a foreign invader and attacks them, creating inflammation and heading to a narrowing of the vessels.
Vasculitis can happen by itself or can be a characteristic of a rheumatic disease, such as rheumatoid arthritis, systemic lupus erythematosus (SLE; lupus) or systemic sclerosis. In difficult cases, patients can promote organ injury or death.
About 100,000 Indians per year are admitted to the hospital because of vasculitis. Vasculitis can influence people of all ages, races, and gender.
Vasculitis happens when the immune system attacks the blood vessels by error. What causes this to occur isn’t totally understood. Sometimes an autoimmune disease triggers vasculitis. Immunological disorders occur when the immune system produces antibodies (proteins) that attack and destroy the body’s tissues or cells.
No one understands exactly what causes immune disorders, but many factors seem to be associated. If you have an immune system disease, learn as much as you can about it. And work closely with your healthcare professionals to maintain it.
