What is the cause of frequent urination?

Whether you are a man or a woman, an old man or a child, as long as you run to the toilet frequently to urinate, people will always laugh at you for having kidney deficiency. So what is the reason for frequent urination? Is it really caused by kidney deficiency? Frequent urination is not a disease, but it is really fatal when running. Frequent urination is not just a simple problem of going to the toilet to detoxify and metabolize. In severe cases, it is a manifestation of kidney failure and may even be life-threatening.

There are many reasons for frequent urination, but it is definitely not a good thing when you urinate frequently. At this time, please pay attention to whether your body is feeling unwell. Find out the cause first and then prescribe the right medicine. If you feel unwell, please seek medical attention in time.

Diseases that cause frequent urination:

(1) Diabetes insipidus: Due to hypothalamic-neuropituitary dysfunction, the secretion of antidiuretic hormone decreases, causing the renal tubular reabsorption function to decrease and causing polyuria.

(2) Diabetes: Due to high blood sugar, a large amount of sugar is excreted in the urine, which can cause solute diuresis; due to the increase in blood sugar, the body increases the amount of water intake in order to metabolize and dilute the blood, which is also a cause of polyuria.

(3) Potassium deficiency: In primary aldosteronism, due to hypothalamic-neuropituitary function, antidiuretic hormone secretion is too low, and the patient shows excessive thirst and polydipsia (daily water intake is more than 4 liters). As urine volume increases, potassium loss in urine increases, causing refractory hypokalemia. The urine volume increases and the relative density of urine is below 1.006. Long-term hypokalemia secondary to various reasons can cause renal tubular vacuolar degeneration or even tubular necrosis, which is called potassium-losing nephritis. Renal tubular potassium reabsorption is impaired, and a large amount of potassium is lost in the urine. Patients show thirst and polyuria. Laboratory tests show that in addition to hypokalemia, impaired tubular function is its characteristic.

(4) Hypercalcemia: In cases of hyperparathyroidism or multiple myeloma, elevated blood calcium damages the renal tubules, causing a decrease in their reabsorption function and resulting in polyuria. It is also prone to the formation of urinary stones, which further damages the renal tubular function and worsens the condition. Polyuria caused by kidney disease is seen in the early stages of chronic renal failure, which is characterized by increased nocturnal urine volume. Polyuria can occur in the polyuric phase of acute renal failure or in non-oliguric acute renal failure, and is a manifestation of renal tubular concentrating dysfunction.

If you do not experience symptoms of frequent urination or pain when urinating frequently, it is caused by drinking too much water. Urinating more than 2500ml in 24 hours a day is called polyuria. People who urinate frequently should remember not to drink large amounts of water or tea and avoid eating foods that are too salty or too sweet, so as to avoid the condition of frequent urination at home.
