Crohn's disease is an inflammatory bowel disease with symptoms of abdominal pain, severe diarrhea, fatigue, weight loss, and malnutrition. The inflammation caused by Crohn's disease often spreads deep into the layers of intestinal tissue, which is both painful and debilitating, and can sometimes lead to life-threatening complications.

The role of the immune system is to protect people from disease and infection. When the body's immune system encounters abnormalities, it can lead to a number of diseases related to the immune system and resistance.

Antigens are simply understood as substances that, when entering the human body, will be quickly recognized by the immune system and produce corresponding antibodies to specifically combine with that antigen. Usually, antigens are a protein, a polysaccharide, but can also be any type of molecule carrying small haptens attached to a carrier protein.

Our immune system is a network of cells, tissues and organs that protect us from invading pathogens, keeping us healthy and able to fight off many recurring infections. When babies are babies, they receive immune cells from their mothers through the placenta and breast milk (if they are breastfed).

Young children are often susceptible to illness when they go to preschool. This is the biggest concern of many parents when considering sending their children to school. Many children have a high frequency of illness, which not only affects their health and growth but also disrupts the entire life and work of the whole family.

Zinc is an essential trace element for all living things. In humans, growth and development are closely dependent on zinc. The nervous, reproductive and immune systems are particularly affected by zinc deficiency, as well as by zinc excess. So how complex is the relationship between zinc and the immune system?

The immune system keeps a record of every germ it has ever fought off, in types of white blood cells (B and T lymphocytes) called memory cells. This means it can recognise and destroy the germ quickly if it enters the body again, before it can multiply and make you feel sick.

The immune system is a barrier with many layers of defense that helps the body prevent pathogens by identifying and destroying foreign antigens, preventing them from harming the body.

Thyroid ultrasound uses sound waves to create images of the thyroid gland in the neck. It is a tool commonly used to examine enlarged thyroid glands, tumors or nodules found in this area, or when the patient has hyperthyroidism or hypothyroidism.

Graves' disease with eye complications is a common problem in people with overactive thyroid. This is an autoimmune disease caused by antibodies directed against receptors found in thyroid cells and also on the surface of cells behind the eyes, causing the eyes to bulge.

Thyroid hormones have a significant impact on cardiovascular function and structure. Accordingly, cardiovascular complications of hyperthyroidism are also one of the common complications of organ systems in the body when this disease is not detected early and treated properly.
