Symptoms of diabetes and thirst?

summary

Diabetic patients with polydipsia and polyuria can be expressed by the following causal chain: hyperglycemia → appearance of urine glucose → increase of urine volume → water loss → increase of plasma osmotic pressure → thirst → polydipsia. The more serious the diabetes, the more obvious the polydipsia and polyuria. The most obvious symptom of diabetes is often feeling thirsty, polyuria, drinking a lot of water is dry, diabetes thirsty symptoms? Let's talk about it.

Symptoms of diabetes and thirst?

If the urine output of diabetic patients is too much and they can't drink enough water in time, when the body water loss reaches 10%, they will feel thirsty, palpitation, fatigue, and blood sugar will rise; If the water loss reaches 20%, there will be irritability, delirium, coma, blood pressure drop, and even life-threatening.

In some elderly diabetic patients, the hypothalamic thirsty center is not sensitive due to cerebral arteriosclerosis, and the body does not feel thirsty when losing water and increasing plasma osmotic pressure.

Due to the inability to drink water in time, osmotic diuresis will continue to cause water loss, and the plasma osmotic pressure will further increase. Patients will have hyperosmotic coma due to diabetes, manifested as fatigue, loss of appetite, vomiting, and in severe cases, irritability, indifference, even coma and shock.

matters needing attention

Therefore, even patients with diabetes usually need to add enough water, should not drink more, at least to meet the physiological function of normal water, that is, when thirsty to drink some water, for the elderly patients who are not sensitive, can make a daily drinking time, drink water on time.
