Squatting and standing up dizziness is mostly caused by postural hypotension. Some people will get dizzy when they squat down and stand up, this is because the blood supply to the head is insufficient, the body will self-regulate, the heart immediately step up its work in order to send the blood up as soon as possible, and it will soon return to normal. If you are a diabetic, you must be careful of hypoglycemia, when blood sugar is not up to standard, hypoglycemia occurs easily when postural hypotension, and hypoglycemia can cause a lot of damage to the body of diabetic patients. If this condition occurs, we should pay attention to the adjustment of preventive medication and regular check-ups. Diabetic patients must have a reasonable diet, not too hungry or too full, and do not engage in physical activities immediately after meals. It is very important to test blood pressure on time every day, which can help us to perceive the change of blood pressure and adjust the medication in time. You should ensure sufficient sleep time, avoid straining and prolonged squatting or prolonged standing, try to keep your movements slow and gentle when you get up in the morning, do some preparatory activities for your limbs after getting up or before exercising and also after squatting toilets, and get up slowly to help blood flow back to the heart. Do not be alarmed by this situation, you should go to the hospital to identify the specific cause of the disease and carry out reasonable treatment.
