Umbilical or inguinal hernias are common (especially as we get older). We stress out the ligaments and tendons in those areas and they can get weak. Too much strain on them and the tissue can start popping through and they can get very uncomfortable. To be safe, get an evaluation with a medical doctor to evaluate the situation and make sure nothing is pinching or cutting off any blood flow to any organs. After that, there are steps you can take to prevent these from happening and to conteract it if they already exist.
There are simple braces now that will hold in an umbilical hernia so the body has time to heal and repair itself. These are beneficial so that the hernia is not straining and pushing through tissue.
There are simple Kegel exercises for strengthening the pelvic floor and the inguinal and umbilical area. The key to any exercise is consistency! You’ve consistently strained and damaged the areas that are herniated, so you’ve got to consistently repair the areas and undo the damage. Putting in the effort to naturally heal the body will definitely be more beneficial than putting a foreign substance (like mesh) into the body to address the hernia. Any time a foreign substance is introduced, there are consequences and toxicity that come along with it. Do everything you can to pursue a real health solution so that your body can do the healing the way it was designed to.
