From the past 2 weeks, i am having following symptoms: 1. Whenever i get up from bed or from sitting i feel light headedness 2. Gas trouble 3. Increased thirst (today i felt this symptom) 4. Stiffness in occupital area of the head. 5. Suddenly i get nervous for no reason 6. Sleep patterns changed, sleep comming after late night, but able to sleep for more than 7 hours. These are the symptoms i am facing, as due to work loads and family issues i am not able to focus on health. I am having a sedentary lifestyle. But no junk foods are consumed. Please guide me for this issue. What to do?. Whether is due to bp or sugar problem?.
