I have constant diarrhoea and gas (last 4-5 months) now. can medications cause this continuously? no blood in stool, no discolouration, but gas and diarrh. my stool is a bit watery (water turns brown) and stool is in small pieces?

Chronic Diarrhea can be a problem. It is important that you have a stool culture to determine if you have a chronic infection such as giardia which can be easily treated with medication. Talk to your primary care provider and have a thorough exam and testing. You can also discuss the effect of any meds that you are taking.

Dr Rhoads agreed

May be other factors: While some medications, like certain antibiotics, may cause diarrhea, your experience unfortunately warrants a healthcare visit to determine the cause. Chronic diarrhea may harm your body’s water and electrolyte balance and potentially suggest or mask an infection. What’s more, diet or other factors may be responsible, so a clinician assessment with two-way communication is important.
