What department should I visit for dark yellow urine?

　　Yellow urine generally can be evaluated by departments including traditional Chinese medicine, urology, nephrology, hepatobiliary surgery, and endocrinology. Detailed explanations are as follows:

　　1. Department of Traditional Chinese Medicine: From the perspective of traditional Chinese medicine (TCM), yellow urine may be related to damp-heat descending or excessive liver fire. The TCM department can provide syndrome differentiation and treatment, using methods such as clearing heat and removing dampness or soothing the liver and reducing fire to improve related symptoms.

　　2. Urology Department: If yellow urine is accompanied by symptoms such as frequent urination, urgency, or painful urination, it may be caused by urinary tract infections or urinary stones. This department can identify and treat the cause through urinalysis, ultrasound, and other examinations.

　　3. Nephrology Department: Abnormal kidney function can affect the composition of urine. If yellow urine is accompanied by increased foam or eyelid swelling, it may indicate kidney diseases such as nephritis. The nephrology department can perform targeted examinations and treatments.

　　4. Hepatobiliary Surgery Department: The liver and gallbladder are responsible for bilirubin metabolism. If bilirubin levels increase due to bile duct obstruction, hepatitis, or other conditions, urine color may darken. This department can investigate whether hepatobiliary diseases are affecting urine color.

　　5. Endocrinology Department: Diabetes patients with poorly controlled blood sugar may experience elevated urine glucose levels, which can alter urine color. The endocrinology department can test blood sugar and urine glucose levels to determine whether the change is related to metabolic disorders.

　　When yellow urine appears, you can first appropriately increase water intake and observe any changes. If symptoms persist or are accompanied by other discomforts, you should choose the appropriate department based on your own symptoms and avoid self-medicating, which may mask the underlying condition.
