The best part of your history is that you have developed the abdominal symptoms 6 weeks ago and have stopped Lithium 2 weeks ago.
Hence both these things do not appear to be connected.
Hence I would advise on both fronts differently.
As for Lithium, you have to follow the advice of your treating Doctor strictly.
As for the GI Symptoms like cramps, diarrhea
, metallic smell in stool the cause can be enteritis
Get the stool tests done for a few days.
Get the blood tests for CBC, thyroid
, liver functions and as required.
X-ray of abdomen and Ultrasonography
of abdomen to start with.
CT scan if required.Consult a Gastroenterologist
for proper clinical evaluation and correlation with reports to get an appropriate diagnosis and get treated accordingly.
Hope I have answered your query. Let me know if I can assist you further.
