A proof of Planckâs theory. Planck presented an example of how his method worked by deriving the equation of state for a monatomic gas, not necessarily in equilibrium, with which he could compare the results obtained from prior efforts in thermodynamics.
Symptoms. Most people feel symptoms of hypoglycemia when their blood sugar is 70 milligrams per deciliter (mg/dL) or lower. Each person with diabetes may have different symptoms of hypoglycemia. You'll learn to spot yours. Early symptoms include: 1  Confusion. 2  Dizziness. 3  Feeling shaky. 4  Hunger. 5  Headaches.
Reactive hypoglycemia (postprandial hypoglycemia) refers to low blood sugar that occurs after a meal â usually within four hours after eating. This is different from low blood sugar (hypoglycemia) that occurs while fasting. Signs and symptoms of reactive hypoglycemia may include hunger, weakness, shakiness, sleepiness, sweating, lightheadedness and anxiety. It's possible to have symptoms that are similar to reactive hypoglycemia without actually having low blood sugar. True reactive hypoglycemia symptoms that are caused by low blood sugar occurring after eating are uncommon.
