Hi,
i am just a med student, so my opinion is not base on experience. You are having chronic diarrhea with floating and foul smelling stool. No fever which might indicate that you are having an infection. However, you constantly feel tired. Depression also presents with continous tiredness. You should know if you are depress. I think that maybe you are having fat and carbohydrate malabsorption.
Common acute causes are :
viral gastroenteritis : sporadic and epidemic diarrhoea.
Food poisoning : s. Aureus and c. Perfringens
traveller’s diarrhoea : e. Coli
bacterial enterocolitis : c. Jejuni, shigella, salmonella and epec
parasites : giardia lamblia, amoeba, cryptosporidium.
Drugs : nsaids and antacids
common chronic causes :
irritable bowel syndrome : contains mucus
infectious diseases : giardia lamblia, aids patients
bacterial overgrowth : normal colonic flora spread to si
post-infectious at small intestines or colon.
Ibd : crohn’s disease and uc
carbohydrate and fat malabsorption
endocrine diseases : hyperthyrodism
laxative abuse
malabsorption can affect growth and development, or it can lead to specific illnesses. Some of the causes of malabsorption include:
* cystic fibrosis (the number one cause in the u.S.)
* chronic pancreatitis
* lactose intolerance
* celiac disease (gluten-induced-enteropathy, sprue)
* whipple disease
* shwachman-diamond syndrome
* bovine lactalbumin intolerance (cow's milk protein)
* soy milk protein intolerance
* acrodermatitis enteropathica causing zinc malabsorption
* biliary atresia
* abetalipoproteinemia
* vitamin b-12 malabsorption may be due to:
o diphyllobothrium latum infestation
o juvenile pernicious anemia
* parasites
o giardia lamblia
o strongyloides stercoralis
o necator americanus (hookworm)
