6 Signs of Low Immune System

| |

In recent months, the importance of a strong immunity system has been a heavily discussed topic.

But this topic should not be important only related to certain health issues, such as a pandemic, but our concern for a strong immunity system should be constant. That said, immunity is our 24-hour protection against diseases, at every moment in life.

What is the immune system?

Your immune system is your body’s defense mechanism that protects you from various types of bacteria, viruses and other microorganisms. Most young and healthy people have an average immune system, but it may not always protect them from disease.

In case your immune system is weakened, you may face minor or major health problems. Your immune system protects you from any infection, and if you have a weak immune system, you are more likely to get allergies, rashes, and so on.

White blood cells play a crucial role in building your immune system. They circulate through the body through the blood vessels to protect you from any viruses and bacterias from the outside. 

What causes a weak immune system?

As mentioned earlier, white blood cells protect you from any infections. However, many reasons can affect the functioning of white blood cells. Some chronic and severe medical conditions can create problems for your immune system, such as:

  •  Cancer
  •  Diabetes
  •  HIV
  •  Malnutrition
  •  Autoimmune diseases
  •  Certain medical treatments

What are the signs of a weak immune system?

If your immune system is weakened, you will experience some (or all) of the following symptoms:

1. Extreme stress

If you are constantly under stress, it can be a sign of a weak immune system. On the other note, it has been confirmed that stress lowers the levels of white blood cells in the body, which also leads to a weakening of the immune system.

2. You have a constant cold

It is common for an adult to catch a cold 2-3 times a year, and for children a couple of times more. It usually takes 7-10 days to fully recover from a cold. But if you catch colds more often and they last longer than average, your immune system is weak. 

3. Digestion issues

In case you often have digestion issues like diarrhea, gas or constipation, chances are high that you have a weak immune system. According to research almost 70% of the activity of the immune system occurs in your digestive tract because good bacteria and microorganisms reside inside. Insufficient number of good bacteria can increase the chances of virus attack, bacterial infections and autoimmune diseases.

4. Fatigue

If you feel tired after sleeping through the night, you have a problem. Fatigue after sleep is not normal. Weak immune system is also reflected in low energy levels. If you are constantly exhausted and have a lack of energy, you have a weak immune system.

5. Infections

People with weak immune system are likely to get infections easily. According to some studies, pneumonia, ear infections and chronic sinusitis are the most common.

6. Slow healing of wounds

Slow healing of wounds is normally a sign of a weak immune system. When you cut or burn yourself, the body sends nutrient-rich blood to heal the wound. But this happens only in the case of a healthy and strong immune system. In case of weak immune system, the wounds heal slowly.
