Could Darker Yellow Urine Today Despite Drinking Water Be Related To Recent Diarrhea, Kaopectate, Or Diet?

Today, I have darker than normal yellow urine. This just happened today. I ate a steak & cheese sandwich last week and got diarrhea and took Kaopetate a couple of times. Last Saturday I had a hamburger and had diarrhea . I took Kaopetate and now for some reason today my urine is a darker yellow and normally pale. . I drink water and it lightens and after that the color is back a darker yellow.I also took Mucinex a few times this week but it did not change my urine color. All day today I had about 5 16 oz waters and the it goes light yellow but in between the water it is back darker

Hello,

Kaopectate can affect the way your intestines absorb water and bile pigments. Take plenty of water while taking this medicine. Normally also you should keep yourself well hydrated. The steak and cheese sandwich and hamburger are high in protein and iron. Proteins digestion releases urochrome pigment that makes the urine yellow.

Your urine may turn darker than normal when you don't drink enough water. Avoid high-protein, salty, or sugary meals until your urine color returns to normal. If dark urine persists more than 2–3 days despite steady hydration. Get clinically examined by a local GP, you require to do liver function tests to rule out liver disorder, liver dysfunction, jaundice, hepatitis, etc.

Start taking boiled water and home made nutritious boiled food to avoid further complication. Avoid taking oily, fatty, spicy food. Avoid taking packaged and processed food. You may take liver tonics. Get tested at the earliest. You will be treated accordingly.

Take care. Hope I have answered your question. Let me know if I can assist you further.
