It is normal for blood sugar to rise after a meal, but some people with diabetes have lower blood sugar after eating than before a meal. What's going on?

In general, people eat and their blood sugar rises, and after the blood sugar reaches its peak 30 60 minutes, the blood sugar will also rise to the peak within 30 60 minutes, which is 5 10 times the base value, and then it will fall, and the blood sugar will increase after 3 to 4 hours, but it will fluctuate within a certain range.

Patients with type 2 diabetes can experience excessive insulin secretion (hyperinsulinemia) and delayed peaks, high insulin concentrations, unable to return to baseline levels, so postprandial blood sugar is low, or even hypoglycemia, if you eat too little, postprandial exercise intensity is too high, patients may also have postprandial hypoglycemia or even hypoglycemic reactions, postprandial blood sugar is significantly lower, or it may be that the dose of hypoglycemic drugs is too large.

How to improve it

1.Go to the hospital to have your insulin or C-peptide checked. If delayed insulin secretion is identified, medication adjustments are required.

2.If low blood sugar after meals is due to insufficient diet and excessive exercise, a reasonable diet and exercise plan must be strictly followed to achieve regularity and quantification.

3.If it is caused by drugs, it is advisable to carefully check whether the drugs taken in addition to hypoglycemic drugs have hypoglycemic effects. If so, communicate with your doctor in time whether you can use other medications instead.

If the dose of hypoglycemic drugs is incorrect, you need to communicate with your doctor to adjust the medication.
