My 93-year Old Husband Has Recently Had A Bout Of

My 93-year old husband has recently had a bout of diarreah (I know it's spelled incorrectly) Went to urgent care...blood work fine....no stool sample since diarreah ceased and he felt fine. However, his appetite has decreased and he has a craving for sweets......also, because of a family trip this weekend, he overindulged in wine and some food, he has had a flare-up of gout. He has never been a heavy beer drinker; wine mostly because of his Italian heritage.....but all weekend, he seemed to want malteds, etc. Any ideas???
