Rocket, if you want to battle it out let's go. I don't use wikipedia, I use my vet, experience, citing medical articles and ratguide.com.
As for "wet tail"... (From

Diarrhea may occur in Syrian hamsters of any age and is known as “wet tail,” although this euphemism is frequently used to describe the disease in young hamsters. Proliferative ileitis is the most significant intestinal disease of 3- to 10-wk old Syrian hamsters and results in high mortality. It is caused by the intracellular bacterium
Lawsonia intracellularis. Treatment involves correcting life-threatening electrolyte imbalance and dehydration, administering antibiotics, and force feeding. Several antibiotic treatments are recommended, including doxycycline (5–10 mg/kg, PO, bid for 5–7 days), enrofloxacin (10 mg/kg, PO or IM, bid for 5–7 days), and trimethoprim-sulfamethoxazole (30 mg/kg, PO, bid for 5–7 days). Symptomatic treatment with bismuth subsalicylate may be given if diarrhea persists. Replacement electrolyte and glucose solutions should be given orally, and electrolyte fluid replacement such as saline or lactated Ringer's solution should be given at a dosage of 20 mL/100 g body wt once daily. Sequelae of proliferative ileitis in surviving Syrian hamsters may include eventual obstruction, intussusception, or rectal prolapse.

Diarrhea in adult Syrian hamsters is associated with
Clostridium difficileenterotoxemia and, as in guinea pigs, may occur 3–5 days after administration of antibiotics such as penicillin, lincomycin, or bacitracin.
The discharge doesn't look like a standard diarrhea which should smell foul (bacteria). Just trying to determine what's going on here. As for the BRAT diet, see if some rice and toast help firm up the poop she is having. Check for bloat, gently feel her belly and feel for lumps inside.
