Patient discussion about weakness

Q. my wife feels weak. her pulse is only 45. What should we do

A. Is her pulse always that low? Is it regular? Does she have periods of rapid pulse?
Is she sensitive to cold weather (e.g. wearing warm clothes when others don't)? Has she gained weight recently?
Has her hair changed? Does she have any heart diseases? Diabetes?

The combination of slow pulse and weakness in a woman (what's her age?) may suggests hypothyroidism. In this case, than she needs to see a doctor in order to diagnose and treat this condition.

A. No!
I suffered from hypothyroidism and had asthenia.
there are many causes for this symptom. Some are psychological but some are physical. Blaming your mental status is the last resort, and if your GP does it before he denies other reasons you need to change your GP!
