Hi, There are other possibilities as well. Seasonal Affective Disorder. Millions suffer from depression, low energy, lowered libido, etc. It is thought to be due to the lack of light, as days get shorter, among other things. If this is an aspect of your husbands ills, then colitis, or ulcerative colitis call be an accompanying stmptom, which would accout for bloody stool. I do also recommend seeing a gastro-enterologist, as well as a psychotherapist. Colitis is well known for being a symptom of internalized and unexpressed emotional difficulties.
