Metformin and Glucose Levels

To E.W., Arley, Alabama:

The hemoglobin A1c level indicates a person’s average blood glucose over the prior three months. It is a better measure of glucose control than a finger stick test that measures glucose at one specific time. In general, taking metformin lowers one’s A1c level. A desirable A1c reading is less than 7 percent. An A1c of 9 percent indicates the average blood sugar level is 240 Side effects of metformin may include GI upset, headache, and weakness. Patients with kidney, liver, or heart problems may experience a rare but serious condition called lactic acidosis.

To A.S.: Long-term use of drugs called proton pump inhibitors (such as Aciphex) for acid reflux is seen by most as a safe choice that is made on a case-by-case basis. There is some evidence that the decrease in acid in the stomach increases a person’s risk of pneumonia. The lower level of stomach acid may also decrease the body’s ability to absorb calcium and vitamin B12, nutrients that are important for bone health, energy, and metabolism.
