Constipation is a messy topic among FOXG1 families. It is very common, as it seems the low muscle tone extends into the smooth muscles (these are the muscles that are controlled by the autonomic system, the system that regulates all your involuntary functions, like blinking, breathing, temperature control, and also digestion) in the digestive tract, causing constipation, slow gastric emptying, etc. Consult your doctor about a fiber rich diet and/or medication to help bowel emptying.
