Hi.
Thanks for your query.
Noted your history of your Father being suffering from severe neuropathy, irregular motion till the medicines are given.
Neuropathy is usually not known to cause such a problem.
Both the problems may be unrelated to each other but most probably the cause may be the same like
diabetes or so.
I would advise him the following:
First of all to get the blood tests to see for any deficiency of B-complex
vitamins, Vitamin D and other tests like
thyroid functions and so on.
Tests of stool for 3 consecutive days.
Ultrasonography of the abdomen.
Medical management of the causative factors. Treatment of neuropathy with injectable b-complexes and supportive medicines like Vitamin D and multivitamins.
For the irregular bowel movements:
Take an opinion of a Gastroenterologist.
Bowel series with barium and other tests as mentioned above.
Once a proper diagnosis is done and well managed he shall get a good control over both the things.
