An increased susceptibility to infections can severely impair the quality of life of those affected. An overview of possible causes and what can be done about them.
Fever, sore throat, pharyngitis or tonsillitis, runny nose, headache, tiredness, feeling of weakness - if these symptoms persist for a long time or occur again and again within a very short time, this can quickly become a great burden for those affected. Failures at work and withdrawal from private and social life are among the consequences. In addition, permanent infections can also promote the development of tumors. In any case, in the case of constantly recurring inflammations and infections, it makes sense to contact the doctor and have a blood count done. In some cases, a nutrient deficiency can also be to blame for the high susceptibility to infections. But other reasons are also possible. Some triggers at a glance:
- Nutrient deficiencies
- Disturbed lymphatic system
- Unhealthy lifestyle

Constantly ill: high susceptibility to infections due to nutrient deficiencies
If the susceptibility to infections persists, it is important for those affected to have a blood count done by the doctor and certain values checked. According to the Federal Center for Nutrition, vitamins A, C, D, E and trace elements iron and zinc are particularly important for a strong immune system. A very low vitamin D level manifests itself, for example, in the form of hair loss, muscle pain, body aches and increased susceptibility to infections. According to the platform internists on the net, an iron deficiency can also trigger an increased susceptibility to infections, fatigue, dizziness, headaches and other symptoms.

Often ill: Researchers discover cause in lymphatic system
However, swollen lymph nodes can also be a possible cause behind colds, flu, tonsillitis and other diseases. One thing is certain: lymph nodes play an important role in defending against infections in the body. If a person is ill, the lymph nodes take up the pathogens, which activates immune cells and stimulates them to produce antibodies. But if germs and pathogens get out of hand, all the more immune cells have to be activated. As a result, the lymph nodes swell and infections occur.
Chronically ill: Unhealthy diet — you should avoid it
Food also has an influence on our health, because an unhealthy diet weakens the intestinal flora. This in turn results in digestive problems and can also lead to frequent infections. Among other things, large amounts of sugar, alcohol, unhealthy fats (trans fats, saturated fatty acids) and red meat should be avoided. Because with regular consumption, inflammatory reactions in the intestine can be set in motion. According to the Robert Koch Institute (RKI), regular consumption of large amounts of red meat also carries a higher risk of colorectal cancer.

On the other hand, vegetables with a high vitamin C content are good for the immune system. This is because vitamin C supports the immune system in its defense work. It is found in cabbage, for example Brussels sprouts, kale or broccoli. Iron-containing foods such as fish, poultry or legumes and nuts as well as probiotic foods such as sauerkraut, yoghurt or kefir also protect against infections.
