Protein deficiency

Introduction to protein deficiency Protein deficiency is a dystrophic disease caused by a lack of protein nutrients. Proteins in body tissues are consumed because of insufficient or excessive protein intake. Mainly manifested as weight loss, fatigue, weakness, diarrhea, anemia, low plasma protein concentration, nutritional edema, dry skin, brown hair and so on. Children also have growth retardation and mental retardation. basic knowledge The proportion of illness: 0.0015% Susceptible population: children and middle-aged and elderly Mode of infection: non-infectious Complications: glomerulonephritis muscular dystrophy

Cause of protein deficiency

(1) The long-term intake of protein nutrients is insufficient or the variety is too single, lacking essential amino acids.

(2) Digestion and malabsorption of protein foods caused by chronic diseases of the digestive tract.

(3) Severe liver, kidney and other organ diseases, resulting in poor protein utilization.

(4) Long-term hyperthermia, hyperthyroidism, tumors, etc. cause accelerated decomposition of proteins.

(5) Long-term loss of protein caused by proteinuria and other patients such as nephritis.

(6) The debilitating state of digestion, absorption and metabolism caused by the low function of various organs of the body. The prevention and treatment of protein deficiency, in principle, in addition to active treatment of related diseases, is mainly to enhance the intake of protein nutrients (see "Protein nutrients"). A compound such as a complex amino acid can be used as necessary.

Protein deficiency prevention

A reasonable diet can take more high-fiber and fresh vegetables and fruits, balanced nutrition, including essential nutrients such as protein, sugar, fat, vitamins, trace elements and dietary fiber, with a combination of vegetarian and vegetarian foods. The complementary role of nutrients in food is also helpful in preventing this disease.

Protein deficiency complications Complications glomerulonephritis muscular dystrophy

Easy to complicated with glomerulonephritis, muscular dystrophy and so on.

Protein deficiency symptoms Common symptoms Decay proteinuria Skin dry diarrhea

Mainly manifested as weight loss, fatigue, weakness, diarrhea, anemia, low plasma protein concentration, nutritional edema, dry skin, brown hair and so on. Children also have growth retardation and mental retardation.

Protein deficiency check

Laboratory examination: urinary albumin clearance, blood viscosity, oxidized acetic acid AS-D naphthol esterase staining, serum sialic acid determination.

Diagnosis and identification of protein deficiency

According to the main performances such as weight loss, fatigue, diarrhea, anemia, low plasma protein concentration, nutritional edema, rough skin, yellow hair and so on. Children also have growth retardation and mental retardation. Then cooperate with laboratory tests for diagnosis.

Need to do the following identification:

1 protein intake is insufficient or poorly absorbed. Loss of appetite and anorexia caused by various reasons, such as severe heart, lung, liver, kidney disease, gastrointestinal congestion, brain lesions, digestive tract obstruction, difficulty in feeding such as esophageal cancer, gastric cancer; chronic pancreatitis, biliary tract disease, Malabsorption syndrome caused by gastrointestinal anastomosis.

2 protein synthesis disorders. Liver damage for various reasons reduces liver protein synthesis and decreases plasma protein synthesis.

3 Long-term loss of large amounts of protein. Gastrointestinal ulcers, acne, hookworm disease, menorrhagia, large-scale wound exudate can cause a large amount of plasma protein loss. Repeated abdominal puncture drainage, end-stage renal disease peritoneal dialysis treatment can lose protein through the peritoneum. Nephrotic syndrome, lupus nephritis, malignant hypertension, diabetic nephropathy, etc. may have a large amount of proteinuria, and proteins are lost from the urine. Digestive tract malignant tumors and giant hypertrophic gastritis, protein leakage gastrointestinal disease, ulcerative colitis, localized enteritis, etc. can also lose a large amount of protein from the digestive tract.

4 protein decomposition accelerates. Long-term fever, malignant tumors, hypercortisolism, hyperthyroidism, etc., cause protein breakdown beyond synthesis, leading to hypoproteinemia.
