Blood sugar 43

Hi, welcome to the ehealth forum and I am glad to help you.
You seem concerned with low blood sugar measured at 43 mg/dl. A person with a documented blood glucose level of less than 45 mg/dl is diagnosed with hypoglycaemia(if Whipple's triad is satisfied), common symptoms of which include weakness, fatigue, lethargy, difficulty speaking, slurred speech, Shakiness, anxiety, nervousness, hunger, sweating, feeling of warmth, negativism, irritability, depression etc. Not all of the mentioned manifestations occur in every case of hypoglycemia.
With the information that you have given, the possibility of reactive hypoglycemia or idiopathic postprandial syndrome is quite likely. Reactive hypoglycemia with demonstrably low blood glucose levels is most often a predictable nuisance which can be avoided by consuming fat and protein with carbohydrates, by adding morning or afternoon snacks, and reducing alcohol intake. Many people find improvement by changing eating patterns (smaller meals, avoiding excessive sugar, mixed meals rather than carbohydrates by themselves), reducing intake of stimulants such as caffeine, or by making lifestyle changes to reduce stress. Uncooked cornstarch at bedtime may be necessary in some patients. You can try these food and lifestyle changes and you might realise that you have got rid of the problem of low blood sugar.
Hope this helps. Take care.
