The body usually gives various signs to show that the immunity and its defences are low and that the immune system lacks the ability to fight infectious agents such as viruses and bacteria. The person can therefore become sick more often and experience symptoms such as frequent chills, fever and recurrent infections.
The immune system is a set of organs, tissues and cells that function together so as to fight invading agents hence preventing attack by diseases.
Signs and symptoms of low immunity
When the body’s defence is low, one may experience various signs and symptoms such as:
- Recurrent infections such as tonsillitis or herpes
- Simple diseases, but that take time to pass or that worsen easily, such as flu
- Frequent fever and chills
- Often dry eyes
- Excessive tiredness
- Nausea and vomiting
- Diarrhea that lasts more than 2 weeks
- Red or white spots on the skin
- Sharp hair loss
Therefore when you notice any of these symptoms, it is important to adopt the measures that purpose to strengthen the immunity. These include taking a healthy diet that incudes foods that strengthen the immunity and stimulate the defence cells of the body.
What can weaken the immune system?
The immune system can be weakened due to various condition such as stress and anxiety. In addition, other chronic illnesses such as AIDS, lupus, cancer and diabetes can also weaken the immune system and increase the risk of attack by other diseases.
Taking immunosuppressive drugs, corticosteroids or antibiotics can also weaken the immune system. It is thus important to communicate to the doctor about the symptoms that are experienced so that the usage of the aforementioned drugs can be suspended or changed, so as to avoid compromising the functioning of the body’s defence cells.
Aside from diseases, immunological factors and use of various medications can also compromise the body’s defence system. This can be due to lifestyle habits such as lack of physical activity, alcoholism, smoking and unhealthy eating.
Low immunity in pregnancy
During pregnancy, it is normal for the immune system to be weakened due to hormonal changes and changes in the woman’s body. It is therefore necessary to avoid infections such as UTIs which may compromise the immune system.
To avoid such complications, it is important to always go for prenatal consultations, consume a diet rich in fruits and vegetables rich in antioxidants such as orange, pineapple, lemon, carrot and cabbage. It is also advisable to take flu vaccines during pregnancy so as to protect the mother and the baby.
How to improve immunity
To improve immunity, you should change you lifestyle habits and invest more in physical activity and improve your eating habits, consuming foods that stimulate proper functioning of the immune system, such as brazil nuts, fish, carrots and spinach.
Moreover, when you experience symptoms of low immunity especially when you have a disease that weakens the immune system, it is advisable to consult the doctor so that you can be given medications that will improve your immunity. The doctor may also need to perform various blood tests so as to evaluate the defence cells. In some cases, the doctor may also recommend using some home remedies such as Echinacea tea, which will act as a supplement for the treatment of low immunity.
