Increased and decreased creatinine in the blood: what is it, the reasons, the norm, a table describing the diet, prevention

Creatinine in the blood is a product of protein metabolism in the human body, which indicates the functioning of the urinary system. With age, its performance may change. In some cases, an excess of the substance level is considered physiological and does not require therapy. Why does creatinine rise or fall, and when does it indicate a problem in the body?

What is creatinine?

It is a low molecular weight nitrogenous substance synthesized by muscle tissue, after which it enters the bloodstream. It is a constituent part of creatine, without which energy metabolism cannot take place.

Creatinine is a breakdown product. It has toxic effects on tissues. It is processed by the kidneys. If this organ is working normally, the substance is simply excreted from the body. But if a malfunction occurs, the level of the product in the blood can rise significantly. Also, its concentration is influenced by the volume of a person's muscle mass. The more muscles, the higher the level of the substance.

Creatinine rate

The content of this decay product in the blood is influenced by gender, age, and the volume of a person's muscle mass. In addition, a norm has been established for people who have one kidney missing or not functioning.

Various laboratory techniques are used to determine the level of a substance:

• biochemical blood test;
• azometry;
• hemorenal tests.

To eliminate the likelihood of error, a few days before the delivery of the analysis, it is necessary to limit physical activity. Meat and other protein products should not be eaten during the day. Before sampling the material, it is worth giving up strong coffee or tea.

Elevated creatinine: causes

Both physiological and pathological causes affect creatinine levels. The fact that the kidneys are not working properly will be indicated by a very high amount of a substance in the blood. With organ dysfunction, there are:

• high fatigue and constant fatigue;
• labored breathing;
• discomfort or pain in the lumbar region;
• thirst;
• swelling;
• violation of diuresis;
• violation of consciousness;
• convulsions.

To make an accurate diagnosis, the doctor will prescribe an additional examination.

Also, the concentration in the blood of this decay product may be increased when:

• dehydration of the body;
• taking certain medications (antibiotics, antifungal medications);
• muscle damage, including mechanical damage;
• hyperthyroidism;
• eating a lot of meat;
• intense physical activity for several days before the test.

Therapy should be aimed at normalizing kidney function. If the increase in indicators was due to diabetes mellitus or hypertension, the doctor will advise you to take medications that can reduce their effect on the body.

But medications are not the only way to lower blood creatinine. A man must:

• follow a special diet;
• drink at least 2 liters daily. clean water;
• stop smoking and drinking alcoholic beverages;
• reduce physical activity.

Decreased creatinine: causes

What does low blood creatinine say:

1. Decreased amount of muscle tissue. It occurs due to a strict low-protein diet, liver disorders, muscular dystrophy.
2. Violation of blood circulation in the kidneys.
3. Heart failure.
4. Cirrhosis.
5. Oncological processes.

It can also decrease during pregnancy, with a sharp weight loss or taking corticosteroids.

To improve performance, you must:

• include in the diet foods rich in protein (meat, dairy products, chicken eggs);
• adhere to a drinking regime, drinking at least 1.5 liters of water per day;
• exercise to increase muscle mass;
• take vitamins.

Prevention of elevated creatinine

To avoid an increase in the level of a substance in the blood, it is necessary to prevent any pathologies that can lead to this (diabetes mellitus, hypertension, oncology). Also, doctors advise:

• eat properly;
• exercise;
• to refuse from bad habits;
• have a good rest;
• monitor your weight;
• avoid muscle injury.

An increase or decrease in the level of creatinine in the blood indicates problems in the functioning of the kidneys and urinary system. Any deviations in the amount of this substance can negatively affect the state of the body. Therefore, for people diagnosed with diabetes mellitus, hypertension, chronic kidney damage, it is important to undergo regular examinations. This will prevent the development of serious complications.
