The main symptoms that may indicate that your immunity is low and your body's defenses are down is when you get frequently ill. So, your body's defenses are less able to fight against parasites such as viruses, bacteria and fungi.
Therefore, you should be aware of symptoms of low immunity, such as:
- Recurrent infections, such as tonsillitis or herpes;
- Simple but time-consuming or easily aggravating diseases such as influenza;
- Frequent fever and chills;
- Dry eyes;
- Excessive tiredness;
- Nausea and vomiting;
- Diarrhea for more than 2 weeks;
- Red or white spots on the skin;
- Severe hair loss;
Moreover, having a weak immune system may also favor the onset of stress, even after a night's sleep or during a vacation.
Your immune system is formed by defense cells and physical barriers in the body, such as skin and the stomach's acidity, which help to prevent the entry of microorganisms or fight infections when the body becomes sick.
What can weaken your immune system
Your immune system becomes weaker during a cold or flu, so it is easier to catch other illnesses such as tonsillitis during these times without there being a severe health problem.
However, if these infections occur very often, it may mean that a disease is developing. Some diseases that naturally decrease the body's immunity are AIDS, lupus, cancer, anemia, obesity, malnutrition and alcoholism, for example.
In addition, your immune system may also be compromised by the use of corticosteroids, immunosuppressive drugs, which are used in organ transplants, during treatment for cancer or with the prolonged use of some anti-inflammatory drugs, such as Dipyrone
Low immunity during pregnancy
During pregnancy it is normal for your immune system to become weaker because of the hormonal and bodily changes you undergo, so you need to follow other cautions so you can avoid problems such as flu and urinary infections.
To avoid complications, it is important to always go to your prenatal appointments, follow a diet rich in fruits and vegetables that are antioxidants, such as orange, pineapple, lemon, carrot and cabbage, and take the flu vaccine during pregnancy.
When to go to the doctor
You should see your GP as soon as you have two or more of the symptoms of low immunity or if you have an illness or risk factors that can weaken your immune system, and if that is the case you need to have blood tests done to check your immunity.
In general, treatment is done with changes in your eating habits, regular physical activity and the use of home remedies such as echinacea tea. See some options to boost your immune system.
