The low urine in the morning is considered to be a physiological factor, such as hot weather, the body’s water is excreted through sweating, when the urine will be less, and more concentrated, and darker. There are also some people who are used to open-mouth breathing and lose most of their water at night when they sleep, so their urine will also be low. Also consider pathological factors, such as chronic renal insufficiency, obstructive kidney disease, including urinary stones, urethral stricture, prostate enlargement disease in elderly men, etc., which can lead to obstruction of the urinary system, resulting in significantly less urine when urinating and more frequent urination. If you are a middle-aged or elderly man who has low urine and frequent urination, you must have a prostate ultrasound to assess whether there is residual urine in the bladder and to clarify whether the low urine is caused by obstruction or hyperplasia before further treatment.
