How to describe medical symptoms in English?

Traveler's diarrhea is very common. Have you been drinking tap water or eating street food?

旅行者腹泻很常见。你有喝自来水或吃街边小吃吗？

How frequent are the bowel movements? Any blood, fever, or severe cramps?

排便多频繁？有没有血、发烧或严重腹痛？

This sounds like a typical case. The most important thing is to stay hydrated. I recommend oral rehydration salts — you can buy them at any pharmacy.

听起来是典型情况。最重要的是保持水分。我建议用口服补液盐——任何药房都能买到。

Loperamide can slow it down for short-term relief — useful if you need to travel. But if symptoms last more than 3 days or you develop fever, we may need antibiotics.

洛哌丁胺可以短期缓解——需要出行时有用。但如果症状超过3天或出现发烧，可能需要抗生素。

You should be improving by then. Take Loperamide before the flight, stay near the aisle, and keep hydrating. Bring extra rehydration packets for the plane.

到那时应该在好转了。飞行前服用洛哌丁胺，坐靠走道的位置，持续补水。飞机上多带几包补液盐。

Imodium — that's loperamide — is the most effective over-the-counter option. Take two tablets at first, then one after each loose stool. Don't exceed 8 tablets in 24 hours.

Imodium——就是洛哌丁胺——是最有效的非处方选择。先吃两片，之后每次拉肚子吃一片。24小时内不超过8片。

Yes, right here. Dissolve one packet in a liter of bottled water. Drink it throughout the day. This will replace the electrolytes you've lost.

有的，在这里。一包溶解在一升瓶装水中。一天内喝完。这会补充你流失的电解质。

Avoid dairy products, spicy food, alcohol, caffeine, and high-fiber foods. Stick to plain rice, crackers, and bananas until symptoms improve.

避免乳制品、辛辣食物、酒精、咖啡因和高纤维食物。坚持吃白米饭、饼干和香蕉直到症状改善。

Probiotics can help restore your gut bacteria. I'd recommend taking them after the acute phase passes — so once the diarrhea slows down. This brand is popular for travel.

益生菌可以帮助恢复肠道细菌。建议急性期过后再服——也就是腹泻减轻后。这个牌子很适合旅行。

Imodium is $9, rehydration salts $6 for a box of 10, and probiotics $15. Total $30. Would you like a bag?

Imodium 9美元，补液盐一盒10包6美元，益生菌15美元。总共30美元。需要袋子吗？
