Building muscle with occasional ibs

Building muscle when suffering with Diarrhoea

So every other week or so i am currently going through a period of stress related diareah which usually lasts for 2 days until next time it happens. Should i try eat more calories and protein when this happens as i go to the toilet straight after eating so it makes me think none of my calories or protein has been digested. Its not the worst diareah ever but it foes not feel ideal
