A friend who suffered from hypertension and told Huazi that he didn’t know if the weather has been cold recently, and he always got up at night to go to the toilet. He said that he had suffered from hypertension for 7 or 8 years, and his blood pressure of has been around 160/100mmHg, but he didn't feel anything abnormal.
Huazi told him that it is best to go to the hospital to check kidney function, because if blood pressure is not controlled well for a long time, it is easy to cause kidney damage, and the initial symptoms of kidney damage are increased nocturnal urine.
1. The mutual influence between hypertension and kidneys
The kidneys, heart, and brain are all important organs that are susceptible to hypertension. The main damage mechanism of is atherosclerosis induced by hypertension, which leads to arterial stenosis of that impairs the organ blood supply . It occurs in the heart, which is coronary heart disease, which occurs in the brain, which is stroke (stroke). It occurs in the kidneys and causes renal insufficiency.
has obvious symptoms when heart and brain are damaged, while kidney damage is relatively hidden and is often overlooked. Because the kidney itself has a strong compensatory function, symptoms will not appear when the damage is not serious.
However, after renal ischemia, the "renin-angiotensin-aldesterol" system (RAAS) will be activated to further increase blood pressure. renal injury and hypertension are mutually causal, forming a vicious cycle of .
2. It is difficult to reverse after kidney function is damaged
The human body has two kidney . The nephron unit in one kidney is about 1 million to 1.5 million. Under normal circumstances, if the human kidneys perform 1/3 of the function, they can meet the human metabolic needs.
After hypertension causes nephron damage, it is difficult to reverse , but when the renal function loss is within 60% to 70%, there will be no obvious symptoms. This gives most people the illusion that high blood pressure has no effect on the body.
However, when obvious symptoms of renal failure are revealed, nephron damage is often more than 70%. At this time, active treatment will be performed. can only try to promote renal function in the current state, but it is almost impossible to reverse renal failure .
3. When there is an increase in nocturnal urine, you need to be vigilant about kidney damage
Prevent hypertension and cause kidney damage. It is the key to control blood pressure in a long-term and stable manner. The diagnostic indicator of hypertension is 140/90mmHg, but if wants to prevent kidney damage, it is best to control blood pressure below 130/80mmHg. The most ideal blood pressure is around 120/80mmHg.
When kidney damage is damaged, the most susceptible to the reabsorption function of renal tubules , so the initial symptom of kidney damage is an increase in urine volume at night, exceeding 1/4 during the day. However, if the number of urination increases but the total amount of urine is not large, it may be urinary tract infection or prostate hyperplasia in men.
4. Hypertension is a period of high incidence of diseases for more than 10 years
Hypertension is a slow progressive disease, and its damage to organs is also a slow process. However, when organ damage is small, symptoms usually do not appear. Generally speaking, various concurrent diseases related to and hypertension often occur in 10 to 15 years after the disease occurs. However, if the blood pressure is super high, cerebral hemorrhage may occur in 3 to 5 years.
So, hypertension should be detected and controlled early, and don’t think there is no damage without feeling. 's "prevention" before illness is far more important than "treatment" after illness .
If kidney damage has occurred, antihypertensive drugs can choose "pril" and "sartan", which can inhibit RAAS and have a good kidney protection effect.
Summary: Patients with hypertension who have been ill for more than 10 years need to pay more attention to their kidney function. If there is an increase in urination at night, beware of impaired kidney function. Keep blood pressure stable at 130/80mmHg for a long time, which has a good protective effect on the kidneys.
The selection and adjustment of antihypertensive drugs need to be carried out under the guidance of a doctor. If you have any questions about medication, please consult a doctor or pharmacist. I am Huazi, pharmacist. Welcome to follow me and share more health knowledge.
