Hi.
Thanks for your query.
Noted the history and understood your concerns.
The history is about you and your husband having stomach pains for a long time.
It looks either there is some problem in eating or drinking things in the family.
Your husband having pain and loose motions in the morning and night may be due to many a factors for which he should undergo the following:
Tests of stool.
Tests of blood.
Ultrasonography of the whole abdomen.
A course of an antibiotic,
metronidazole may help.
If it does not go for
Colonoscopy and CT scan of the abdomen.
Clinical evaluation by a Gastroenterologist for a proper diagnosis and further management.
This applies for your problems too.
Also needed is to stop outside food, canned foods.
Use only boiled and cooled water.
Probiotics and activated
charcoal also helps in symptomatic relief.
IF all the investigations are normal then the most probable reason can be IBS that is
irritable bowel syndrome and should be treated accordingly, reducing the stress and anxiety.
