8 months post-op. When I gag my stomach tightens like a Charlie horse. Can there be something wrong internally?

Dear DesLynn83,
it is hard to tell for sure but based on your description, it sounds like you have muscle spasms. However, without a proper assessment it would be difficult to determine what is wrong. It is best that you visit your plastic surgeon for further assessment. Only after thorough examination you can get proper recommendations and advice.

Hello Des,Great question. Based on your description, it seems as you get a muscle spasm when you gag. I will suggest following up with your surgeon.

Thank you for sharing your question and I am sorry to hear of the muscle spasms.  Some patients can have activation of their stomach muscles like a cramp that can develop in the legs.  Typically this improves over time and fully resolves once your results and tissues fully heal.  If this has not, see your surgeon for an in-person discussion and evaluation.  

Thank you for your question. This sensation your having is unusual. This sounds like a muscle spasm but why this occurs while brushing your teeth is unexplainable. At 8 months, you should be well healed. from your tummy tuck. I would see your family doctor to work up this problem if it continues. Medical issues such as a hiatal hernia or reflux esophagitis could be reasons but further testing will be needed.

You may want to have your PCP run some blood work to make sure that all of your micronutrients (vitamins and minerals) are in normal range. Make sure that you have adequate hydration. You may incorporate gentle stretching exercises that can help with this as well.
