Ammonia-Smelling Urine: A Sign of Dehydration 💧 One of the most common causes of strong-smelling urine is dehydration.

Sweet or Fruity Smell: Possible High Blood Sugar 🍎 If your urine smells sweet or fruity, it could be a warning sign of high blood sugar levels, often associated with Diabetes. Why it happens: Excess glucose spills into the urine, altering its odor. Watch out for other symptoms: Frequent urination Increased thirst Unexplained fatigue ⚠️ Important: If this smell persists, consult a doctor for blood sugar testing. 3.
