Why is my urine very yellow and has a strong odor?

Dark yellow urine with a strong odor may be caused by various factors. 1. Dehydration is a common cause; when the body lacks water, urine becomes concentrated, appearing dark yellow and possibly having a strong ammonia-like smell. 2. Diet can also affect urine color and odor. For example, consuming large amounts of B vitamins or certain spices, such as asparagus, may lead to changes in urine appearance and smell. 3. Certain medical conditions, such as urinary tract infections, liver disease, or diabetes, may also cause darker urine and a stronger odor. If you consistently notice abnormal urine, especially when accompanied by other symptoms such as frequent urination, urgency, painful urination, or fever, you should seek medical attention promptly.
