Hello. Thanks for writing your query to us.
I am really sorry for the condition you are suffering with.
Based on the symptoms and the lab reports you have provided, I suspect you to be suffering with Irritable bowel syndrome. First let me explain in detail about this condition. IBS is a condition characterized by long lasting abdominal pain, changes in bowel habits like diarrhea, and bloating. It is a diagnosis of exclusion, where the individual is diagnosed with it after excluding all other conditions having similar picture. The points that are favorable in your case for this condition are:
1)Your sex- females are 3 times more prone to this
2)Your age (>50. I assumed as you attained your menopause)
3)post menopausal status associated with stress
4)Ruling out of other diseases like Thyroid disorders, colon cancer etc
5)Negative biopsy report
I would like to recommend the following:
1)Avoid outside food.
2)Try to identify foods that you are allergic to and try to avoid them
3)Drink plenty of water
4)Diet a good amount of fibre food to add bulk to the stool.
5)Medications laxatives for constipation and antispasmodics like hyoscyamine for pain abdomen
6)Probiotics like Lactobacillus, buttermilk which is rich in lactobacillus.
7)Psychotherapy as this a disease is considered to have some incoordination between the mind and body.
8)Stress relief like simple exercises, morning walks
9)Yoga It is stated that exercise poses involving the lower abdomen are useful
Above all, I strongly recommend you to consult a physician for the confirmation of diagnosis and a dietician for a perfect diet schedule.
Hope this helps
