Diabetes mellitus is a metabolic disease characterized by hyperglycemia due to abnormal secretion of insulin or impairment of other physiological functions in the body. Long-term high blood sugar can cause chronic damage and dysfunction of the eyes, kidneys, blood vessels, heart and other tissues and organs in diabetic patients.

Diabetes in humans is related to genetic and environmental factors. The main clinical manifestations of type 2 diabetes areFatigue and obesity, while type 1 diabetes is characterized by eating more and more food but weight loss.

1. Why are people with diabetes prone to infections?

Patients with diabetes are prone to a variety of infections, such as urinary tract infections, skin infections, lung infections, etc., these are all due to the high blood sugar of the patient, which leads to metabolic disorders and decreased resistance of the body.

In addition, the body with high blood glucose concentration is equivalent to the natural culture medium of bacteria, which is conducive to the growth and reproduction of bacteria.< span>So once you have diabetes, it is very harmful to the body.

Second, 4 kinds of “must-prevent” infections in diabetic patients

< strong>1. Urinary tract infection

Due to the large amount of glucose in the urine of diabetic patients, bacteria in the urine Bacteria can easily lead to urinary tract infections after entering the urethra.

In addition, diabetic patients have low resistance and poor bactericidal ability, and are prone to secondary neurogenic bladder. Causes urinary retention, which allows bacteria to multiply in the bladder, which can lead to urinary tract infections.

2. Skin infections

The long-term presence of high concentrations of glucose and metabolites in the body, reduces the number of white blood cells in the body and weakens the ability to phagocytose pathogens, which is the main reason why patients with diabetes are prone to skin infections .

At the same time, due to high blood sugar concentration,skin and mucous membranes are in a state of long-term dehydration and chronic hypoxia , the skin barrier function is damaged, resulting in various skin diseases.

3. Lung infection

Diabetic patients are prone to pulmonary infection because most of the diabetic patients are elderly. Due to the high glucose content in the blood, the immune system’s ability to clear pathogens is weakened, coupled with the gradually weakened lung function and the body’s glucose metabolism disorder, making the elderly. Patients are in a state of negative nitrogen balance, so diabetic patients are more prone to lung infections than the general population.

4, Foot infection

diabetes is easy to be complicated by vascular disease, leading to obstruction of blood flow, resulting in decreased distribution of antibodies, which in turn affects leukocyte phagocytosis of pathogens If there is a wound on the foot at this time, it is prone to infection.Because of the poor blood circulation in the body, the tissue at the end of the extremity is deficient. Hypoxia.

If the wound persists and the infection remains unresolved, the tissue will gradually die, Foot amputation should be considered at this time.

Patients with diabetes need to be alert for skin infections, urinary tract infections, lung Complications such as external infection and diabetic foot, and long-term control of blood sugar, pay attention to adjusting the diet structure, drink more water, eat less or not eat high-sugar, high-fat and high-salt foods, Monitor blood sugar regularly, and take medicine or insulin as prescribed by your doctor to avoid further aggravation.
