Causes of low immunity

Some situations that can weaken the immune system are poor diet, poor hygiene habits, not getting vaccinated when necessary, and smoking. In addition, during pregnancy it is normal for the immune system to weaken, which happens naturally in all women as a way to prevent the mother’s body from rejecting the baby, and during treatment for cancer or HIV.

People who have certain syndromes or other diseases such as lupus or malnutrition also have a less efficient immune system and become ill more frequently. The use of certain medications, such as corticosteroids, immunosuppressants used in organ transplants, during cancer treatment or with prolonged use of some anti-inflammatory drugs, such as Dipyrone, also reduces the body’s immunity.

How to know if your immune system is weak

The immune system is made up of the white blood cell, which is responsible for producing antibodies whenever the body is exposed to a foreign body, such as a virus or bacteria. However, it can also be considered that the defense mechanism is made up 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.

A weakened immune system is characterized by an increase in the number of times a person gets sick, suffering from flu, colds and other viral infections such as herpes very frequently. In this case, it is likely that your body is not able to produce defense cells efficiently, which makes it easier for diseases to set in.

In this case, in addition to being routinely ill, the person may present symptoms such as fatigue, fever, and have simple illnesses that easily worsen, such as a cold that turns into a respiratory infection, for example.
