Causes of renal insufficiency

Renal insufficiency has become a very common clinical disease. It has many manifestations and must be treated in a timely manner, otherwise it will affect other organs and cause many complications. There are many causes of renal insufficiency, and there will be some adverse reactions in the gastrointestinal tract. Nausea and vomiting are very obvious. Let's take a look at the causes of renal insufficiency.

Everyone should know what renal insufficiency is. When renal insufficiency occurs, some abnormal phenomena will occur in the body, some gastrointestinal diseases will occur, and it will also have a great impact on the mental state. Everyone should actively understand the causes of renal insufficiency.

The causes of renal insufficiency can be summarized as follows:

1. Kidney diseases: such as acute and chronic glomerulonephritis, pyelonephritis, renal tuberculosis, acute tubular degeneration and necrosis caused by chemical and biological poisons, kidney tumors and congenital kidney diseases.

2. Extra-renal diseases: such as systemic blood circulation disorders (shock, heart failure, hypertension), systemic metabolic disorders (such as diabetes) and urinary tract diseases (urinary stones, tumor compression), etc.

Stage symptoms

Renal insufficiency can be divided into four stages:

First issue

Renal function reserve compensation period. Because the kidney has a large reserve compensatory capacity, although the renal function is reduced clinically, its ability to excrete metabolites and regulate water and electrolyte balance can still meet normal needs. There are no clinical symptoms, and renal function tests are also within the normal range or occasionally slightly higher.

Second issue

Renal insufficiency. The glomeruli have been severely damaged, 60%-75%. The kidneys have some difficulty excreting metabolic waste, and creatinine urea nitrogen may be high or exceed normal values. Patients may experience anemia, fatigue, weight loss, and difficulty concentrating. But it is often ignored. If there is dehydration, infection, bleeding, etc., obvious symptoms will soon appear.

Third issue

Renal failure stage. The kidney function has been severely damaged, 75%-95%, and cannot maintain the stability of the body's internal environment. The patient is prone to fatigue, weakness, inability to concentrate and other symptoms have worsened, anemia is obvious, nocturia increases, blood creatinine and urea nitrogen increase significantly, and acidosis is often present. This stage is also called the azotemia stage.

Fourth issue

Uremic stage or end-stage renal insufficiency. At this stage, glomerular damage has exceeded 95%, and there are serious clinical symptoms such as severe nausea, vomiting, oliguria, edema, malignant hypertension, severe anemia, itchy skin, and a foul smell of urine in the mouth.

The cumulative causes of renal insufficiency are very important. Only by knowing the causes can we understand some targeted treatments. Everyone should pay attention to the phenomenon of renal insufficiency and be able to treat it in time. If the treatment is not timely and the condition is delayed, it will cause more serious kidney diseases. If it develops into uremia, it will be very serious.
