Cold feet

This is harmless. However, if the cold feet hurt when you move, you should consult a doctor. It could be due to a vascular disease. However, winter weather and low blood pressure are usually to blame.

Torn corners of the mouth

They can be very painful and often heal poorly. They are a typical sign of a lack of vitamins and minerals such as iron. However, an allergy or an infection with herpes viruses or bacteria can also be possible.

Severe thirst

If you drink enough and still feel thirsty, you should be examined by a doctor. Kidney problems or diabetes are often accompanied by an increased feeling of thirst.

Dry eyes

Prolonged work at the PC, draughts or even the wrong cosmetics can cause itching and burning. The eyes also become dry if you don't drink enough during the day. However, the signal may also indicate hormonal fluctuations or an illness such as diabetes.

Splintering fingernails

In most cases, splintering fingernails are a sign that the body is lacking important minerals and trace elements such as magnesium and iron. The GP will prescribe preparations to correct this deficiency.

Dizziness attacks

There are many reasons for sudden dizziness: high or low blood pressure, cardiac arrhythmia, hypoglycaemia, a disease of the auditory nerve or depression can cause dizziness.
