Why is my urine yellow and smelly, and what should I do?

　　Yellow urine with a strong odor may be caused by insufficient water intake, consumption of specific foods, urinary tract infections, cystitis, hepatobiliary diseases, diabetic ketoacidosis, and other conditions. It can usually be managed through general treatment, medication, and other approaches. If abnormalities persist, prompt medical attention is recommended. Detailed explanations are as follows:

　　1. Insufficient water intake: When water intake is inadequate, urine becomes concentrated, increasing the concentration of metabolic waste in the urine, resulting in yellow-colored urine with a stronger odor. It is recommended to increase daily water intake, maintain sufficient hydration, promote urine dilution, and improve the condition of yellow urine with strong odor.

　　2. Consumption of specific foods: After consuming large amounts of foods such as carrots, garlic, and onions, pigments or sulfur-containing compounds may enter the urine, causing the urine to turn yellow and emit a distinct odor. It is recommended to reduce the intake of such foods and observe whether urine condition returns to normal.

　　3. Urinary tract infection: Pathogens such as bacteria invade the urinary tract and multiply in areas such as the urethra and bladder, triggering an inflammatory response, which causes urine to turn yellow with a fishy smell. Symptoms may include frequent urination, urgency, and painful urination. Doctors typically recommend treatment with medications such as Levofloxacin tablets, Cefuroxime Axetil tablets, and Sanjin tablets.

　　4. Cystitis: Inflammation of the bladder caused by bacterial infection or irritation leads to damage of the bladder mucosa, with inflammatory secretions mixing into the urine, resulting in yellow-colored urine with a noticeable odor. It is recommended to take medications such as Norfloxacin capsules, Amoxicillin capsules, and Nitrofurantoin enteric-coated tablets under a doctor's guidance.

　　5. Diabetic ketoacidosis: In patients with diabetes, insufficient insulin in the body accelerates fat breakdown, producing a large amount of ketones. These ketones enter the urine, making it dark yellow with a rotten apple-like smell. Symptoms may include excessive thirst, fatigue, and others. It is recommended to use medications such as Insulin injection, Potassium Chloride injection, and Sodium Bicarbonate injection under a doctor's guidance.

　　In daily life, maintaining good habits is important, including adequate water intake, personal hygiene, balanced diet, and regular health check-ups, to support urinary system and overall health, reducing the occurrence of abnormal conditions such as yellow urine with a strong odor.
