In the last 6 months or so, I've experienced a rapid weight loss and also muscle loss. I'm a 68 year-old woman in good general health, but during this time I've had several bouts of diverticulitis. I was on a super dose of amoxicylin antibiotic while hospitalized for one night. I haven't had any diverticulitis symptoms for about a month, but I'm having trouble gaining the weight and muscle back. I've been taking a replenishing probiotic for several days. Should I be considering something other than the diverticulitis as being responsible for this weight and muscle loss? Thank you.
