Normal fresh urine is light yellow because it contains a yellow urine pigment. If it's summer, it's hot and hot, as long as you exercise a little, you'll sweat immediately. In order to cope with the large amount of water loss from sweat glands, kidneys must concentrate urine to preserve water, so urine becomes thicker and less.

If it is yellow urine caused by urinary tract infection, the possible symptoms include urgent urination, frequent urination, dysuria, pain and burning sensation during urination, abdominal discomfort, backache, fever and chills. If urinary tract infection is suspected, urine analysis, urine bacterial culture, X-ray and B-ultrasound can be arranged according to the condition. If you have yellow urine, you should first consider whether you are not drinking enough water, sweating too much, taking medicine, etc. If you urinate yellow only once or twice, and you don't feel uncomfortable, don't worry.
