Hi, may I answer your health queries right now ?  Please type your query here...Hi, My husband yawns excessively; he is often very tired. He also has problems with body temperature regulation- gets cold easily, sweats a lot. Even during the coldest night he will fall asleep with just one blanket but then wakes up feeling cold and needs more bedding. If he falls asleep with too much bedding, he wakes up overheated very soon.He also suffers from high blood pressure despite being very slim, eating healthily, not smoking or drinking. Can all of these be linked?

### output:

Hi! I can understand your concern for your husband. If a patient arrives in my clinic, I would advise and suggest:1. Yawning is many times a sign of low blood sugar. As you say, he feels tired, which indicates low sugar levels available to the brain .2. He has frequent body temperature changes. Normally, the body temperature varies with day and night, but the changes you mention are more than normal3. As you rightly said, slim stature, temperature changes, high blood pressure can be directly or indirectly linked.4. Slim, non-smokers can also have High blood pressure.5. Please get him examined for his blood pressure control. It should remain within normal limits. If needed, his medicines can be changed.6. Please check his blood sugar levels. The tiredness may be related to insulin insensitivity, i.e. Diabetes. Though he is slim, there are lean Diabetics also.7. Please check his thyroid levels. Thyroid problems can also have tiredness, fatigue, temperature changes. 8. Please consult your local physician with the reports. If there are any other health issues, they also need to be corrected with blood pressure. With the control of these factors, his complaints will definitely reduce. Please feel free to consult. Wish him a speedy recovery.
