Feeling weak and tired, despite of having a proper diet and sleep. I am getting bruises and localized infections on skin easily, even with a minor scratch or without any scratch since a few months, because of which I have to take antibiotics in case of infection, after consulting a doctor. Also I feel thirsty very frequently. Cannot control my hunger. I feel hungry suddenly and then it becomes uncontrollable with dizziness. Sometimes, for no reason, I feel dizzy or as if I am losing balance for a moment. What steps should I take?
