Causes of low immunity
Some situations that can cause the immune system to weaken are poor diet, poor hygiene habits, not being vaccinated when necessary, and smoking. In addition, during pregnancy it is normal to have a drop in the immune system, which happens naturally in all women, as a way of preventing the mother's body from rejecting the baby, and during treatment against cancer or the HIV virus.
People who have a syndrome or other diseases such as lupus or malnutrition also naturally have a less efficient defense system and get sick frequently. The use of certain drugs, such as corticosteroids, immunosuppressants used in case of organ transplants, during cancer treatment or with the long-term use of some anti-inflammatory drugs, such as Dipyrone, also decrease the body's immunity.
How to know if the immune system is weak
The immune system is composed of the white portion of the blood, responsible for producing antibodies whenever the body is exposed to a foreign body, such as viruses or bacteria. However, it can also be considered that the defense mechanism is composed of the skin itself and the acid secretion of the stomach, which often neutralizes microorganisms present in food, preventing them from developing inside the human body.
What characterizes a weakened immune system is the increase in the number of times a person gets sick, with flu, colds and other viral infections such as herpes, very often. In this case, it is likely that your body is not able to produce defense cells efficiently, which facilitates the installation of diseases. In this case, in addition to being routinely sick, the person may have symptoms such as tiredness, fever, and have simple diseases that get worse easily, such as a cold that turns into a respiratory infection, for example.See more symptoms that indicate low immunity.
