Does insulin need potassium supplement?

summary

Insulin, presumably we are not unfamiliar with, insulin is essential for diabetic patients, diabetic patients are through the injection of insulin to achieve lower glycemic index. But when injecting insulin, many people will have some misunderstanding. Many people have their own wrong understanding of insulin. For example, some people think that the time of insulin injection is fixed, and others think that insulin injection will be addictive. These are all wrong. Some people even think that insulin injection is only for persistence, regardless of efficiency. So does insulin need potassium.

Does insulin need potassium supplement?

1. Insulin can synthesize glycogen and activate Na + - K + - ATPase on cell membrane, which can promote a large amount of extracellular potassium transfer to cells and produce potassium deficiency in body fluid. Due to the long-term large dose insulin injection therapy in elderly patients with diabetes, the transient excess of insulin will produce islet effect and lead to hypokalemia.

2. When the blood glucose is higher than the renal glucose threshold, a large amount of glucose enters the urine, the urine osmotic pressure increases, and the osmotic diuretic effect causes a large amount of blood potassium to be discharged from the body through the urine, causing the decrease of blood potassium. At the same time, hyperglycemia can also stimulate the secretion of insulin and adrenaline, make blood potassium into cells, reduce the level of blood potassium.

3. Diabetic patients should insist on using insulin, and must use the right method. They should start from some daily trifles, do more exercise, avoid diet, eat more light vegetables and fruits, and eat less sweets. Besides, insulin injection should use syringes. Generally, injection is useless.

matters needing attention

In mild hypokalemia (3.0-3.5 mmol / L) patients, oral potassium supplementation can avoid the sudden rise of serum potassium, the effect is mild and the effect is good. However, it should be noted that potassium chloride tablets and budaxiu enteric coated tablets are not easy to take for a long time because they may cause small intestinal ulcer and necrosis. Patients with moderate to severe hypokalemia (less than 2.9 mmol / L) generally need intravenous potassium supplement. The concentration of potassium supplement should not be too high, and the speed should not be too fast, so as not to cause hyperkalemia.
