A1C normal for 4 years, should I ask doc to reduce cause I feel I'm gaining weight the longer I'm taking it, but I have no other side effects. Weight gain is not a phobia/image thing it's a health concern only because I'm taking gabapentin 900mg 3xday. see my concern

I am a registered dietitian and have counseled and educated diabetics for years. I hope I can offer some help but feel I need to know a little more about your medical issues if you would like to send me a private question. Metformin acts in the following ways: 1) increases muscle glucose uptake by helping with insulin resistance so the glucose absorbed into your blood stream from carbs you eat attaches to insulin receptors and is delivered to cells for energy rather than remaining in your blood stream and 2) decreases glucose production from your liver. When people are first started on Metformin, many experience a sudden weight loss, usually 5-10 pounds, then as your body adjusts to medication, the weight loss stops in most instances. Without knowing what else is going on, the only thing off the top of my head is although Metformin is known to help with weight loss because it controls insulin levels, it can work in the opposite ways as well.
If you have stable sugar levels it may trigger your brain to tell you that you need to ingest sugar because it acts as though you need to eat more (or cause signs of low blood sugar) to stabilize levels, then the liver dumps out more glucose and insulin resistance is exacerbated. Thats the only thing i can come up with with the information you provided. What is your A1C? You stated it was normal, but low end of normal or mid? So this could be going on and perhaps by decreasing the dosage, it may help with this adverse effect, of course talking with your doc first. If you have found any of this useful, send me a private question and give me a more detailed medical history, including how long you've been on that dosage, other meds, A1C, when you were diagnosed, etc?
I am new to this site as well and know it can be intimidating, but I'd love to help if I could as this is my field. I'm easy to talk to and willing to do some additional research for you once I know a little more :) Gabapentin does unfortunately cause weight gain but maybe they aren't related in your case. I wish you the best of luck in finding helpful answers and greatly welcome anything you'd like to send me privately if you're more comfortable doing that.
