I just had a colostomy takedown and its been about a month since then but every time I eat or sometimes after I drink something I will get sick and have to vomit. its only a little bit and sometimes its a white foam and a lot of mucus. i did have pneumonia(a small line) when i left the hospital but i took antibiotics for that. i did get a cold or something a week after i got out and i have a cough that ive had for three weeks now.
