Why do I faint after drinking and urinating?

Fainting while urinating after drinking is an important symptom of urinary fainting, and this disease is also called micturition syndrome. There are many reasons that lead to this symptom, such as hypotension, arrhythmia, increased chest pressure, cerebral ischemia, autonomic nervous system dysfunction, etc., which are the main causes of this disease. For patients with urinary fainting, there are many things they need to pay attention to in daily life, which will be introduced in detail below.

1. Pathological description

As to what causes micturition syncope, there is no consensus yet. However, most experts believe that the disease is mainly caused by vasodilation and contraction disorders causing hypotension, autonomic nervous system dysfunction, arrhythmia, blood pressure fluctuations, and excessive breath holding during urination which increases chest pressure, resulting in temporary insufficient blood supply to the brain. It is these factors that affect the patient's heart's blood output, causing the patient's brain ischemia and fainting. The patient can wake up on his own about two minutes after fainting, and there will be no sequelae.

2. Prevention and Treatment

Although the prognosis of micturition syncope is good, and most patients will stop having the disease on their own as they age. However, since the patient may suddenly faint when the disease occurs, it is easy to cause trauma, and in severe cases it may be life-threatening. Therefore, it is very important for patients to prevent fainting. Clinical practice has shown that the effective measures for preventing and treating this disease are mainly:

① When the patient gets up to urinate, he should sit down first and then stand up slowly. Take deep breaths when urinating (to avoid excessive breath holding).

② Don’t hold your urine. When you feel the urge to urinate, urinate as soon as possible. Men who experience frequent syncope can urinate while squatting or sitting.

③ Actively treat various chronic diseases such as neurasthenia, pulmonary tuberculosis, and gastric and duodenal ulcers.

④ Participate in more sports activities to enhance your physical fitness.

⑤Avoid excessive drinking and overwork.

⑥ Patients can take atropine or 654-2 orally during frequent attacks of this disease.

⑦ After the patient faints, he should be laid flat immediately, and then the patient's Ren Zhong, Nei Guan and Zu San Li acupoints should be pressed with fingers to wake him up as soon as possible. It should be noted that if the patient is suspected of having craniocerebral trauma or cerebral hemorrhage, he should be sent to the hospital for diagnosis and treatment immediately to prevent accidents.

3. Notes

1. For people who have frequent urination, they should drink less water before going to bed, and sit for a while before standing up when getting up to urinate to improve the body's response.

2. Do not urinate too quickly or too violently. If you experience symptoms such as dizziness, blurred vision, palpitations, or weak legs when urinating, you should immediately grab an object or change to a squatting position to urinate.

3. People who have had urinary syncope in the past should squat when urinating.

4. Patients with pulmonary tuberculosis, neurasthenia and deficiency of both qi and blood are prone to this type of syncope. In addition, physical weakness after illness, excessive fatigue and drinking can also induce this disease.
