thin

Introduction

Introduction Weakness refers to the sudden weight loss caused by diseases or certain factors in the human body, and the body fat and protein decrease. When it is less than 10% of the standard weight, it is thin. Some people think that those who are 10% or more lower than the standard weight are lean. Less than 20% is called weight loss). The squalor referred to here is generally progressive in the short term, with weight values measured before and after weight loss, and obvious clothes become loose, the belt becomes loose, the shoes become larger and the subcutaneous fat is reduced, the muscles are thin, the skin Relaxation, bones and other circumstantial evidence. As for the weight loss after dehydration and edema subsided, it cannot be called stagnation.

Cause

Cause

1, hyperthyroidism

If your food intake has not decreased, but your weight has been reduced again and again, accompanied by a thick neck or palpitation, insomnia, etc., you may have hyperthyroidism. Experts say that elderly patients with hyperthyroidism are not as easy to identify as young people, and about one-third of patients have no goiter, and their main performance is getting thinner.

2, cancer

Such as colorectal cancer, pancreatic cancer and so on. Early symptoms of cancer are not obvious, but weight loss is definitely one of them. Gastrointestinal surgery experts pointed out that in the case of colorectal cancer, it may also be accompanied by painless blood in the stool. People over the age of 50 should be vigilant.

In general, once a tumor is diagnosed, it may be advanced. Therefore, if you find that your body weight has declined for unknown reasons, or if someone around you says this, you should be vigilant. "Tumor growth requires nutrition, it competes with other organs of the body for nutrition, which makes it easy to lose weight."

3, diabetes

According to experts, the early manifestations of diabetes are polyuria, polydipsia, and more food, accompanied by weight loss. Experts pointed out that this is caused by the lack of sufficient insulin in the patient's body to fully utilize the glucose in the blood. The body always needs energy. If you can't use glucose, you only need to consume fat, which causes the sudden weight loss.

(1) Weight measurement

It should be done regularly and compared with the standard weight to understand whether the weight loss is progressive, and the common diseases that cause weight loss are diabetes, hyperthyroidism, malignant tumors, etc.

(B) detailed physical examination can often prompt early diagnosis clues.

1, for the thinner should measure body temperature, blood pressure and heart rate, for long-term fever should consider chronic infection, tumor, connective tissue disease, hyperthyroidism, pheochromocytoma. Patients with hypertension (paroxysmal or persistent) should consider pheochromocytoma.

2, the examination of the mouth, skin, hair, lymph nodes, etc.: pay attention to whether there is malnutrition, vitamin deficiency, anemia, edema and so on. The anterior pituitary dysfunction in patients with skin pigmentation, hair loss, pubic hair is more obvious, the skin is pale, dry, dull and genital atrophy, women have breast atrophy. Adison patients have skin pigmentation, lip and oral membranes are a little flaky blue-black pigmentation, and the skin is more exposed to exposed areas, pressure and friction parts, early dizziness, perineum, and abdominal white lines. Patients with hyperthyroidism have warm, moist and sweaty skin, tremors when the tongue and hands are stretched out, heart rate is accelerated, heart sounds are hyperthyroidism, etc., and signs such as goiter and exophthalmos may be present. Patients with carcinoid syndrome may have paroxysmal asthma, skin flushing, right heart valve murmur and hepatomegaly. Skin purple spots, swollen lymph nodes, etc. should consider blood diseases and malignant tumors.

3, other systems of inspection: such as chest, abdomen and nervous system examination are important clues for early diagnosis.

Diagnosis

Differential diagnosis

Simple weight loss includes constitutional wasting and exogenous wasting. Institutional wasting is mainly non-gradual weight loss and has certain heritability. Exogenous wasting is usually affected by various factors such as diet, lifestyle and psychology. Insufficient food intake, partial eclipse, anorexia, missing meals, irregular life and lack of exercise, eating habits and work stress, mental stress and excessive fatigue are the causes of exogenous wasting. Simple upper body weight loss is a manifestation of progressive lipodystrophy. Progressive lipodystrophy is a rare autonomic nervous system disorder characterized by adipose tissue metabolic disorders. The clinical and histological features are slowly progressive bilateral distribution with substantially symmetrical, well-defined, subcutaneous adipose tissue atrophy or Disappeared, sometimes combined with limited adipose tissue hyperplasia, hypertrophy.
