Dear User!
The causes of the symptoms mentioned like feeling of heat, pricking sensation,
sleeplessness, bloating,
constipation at the age of 62 years may be due to various causes combined or individual problems like Thyroid problems,
Diabetes, menopausal causes, dietary habits, vitamins deficiency, etc. I noticed that you mentioned about some blood tests. I wonder if the workup for thyroid function was done and if she was evaluated for diabetes. Considering normal
endoscopy and
Ultrasound reports I assume that she has no local issues with the gastrointestinal system and thus the other factors should be considered, as mentioned earlier as hormonal causes and vitamin deficiencies, etc.
So, a further follow up with the doctor with the mentioned complaints and tests like TFT, FBS, PPBS, Vit B levels, etc. may be helpful. Taking vitamin supplements would also be helpful if she is not on any so far.
Hope that helps! Please feel free to write back!
