Thank you for your reply.
You have a condition called abdominal umbilical hernia. It is usually not a problem, unless other complications are associated with it. When there is complication that make the hernia cause discomfort/pain, such as abdominal tissue strangulation inside the hernia, it may become necessary to repair the hernia. However, if you are not in pain or experiencing other discomfort, the hernia is often not repaired.
As I menioned, complications may develop if pressure inside the abdomen resulting from daily activity or weight gain pushes the abdominal contents further through the opening. Such body changes can cause abdominal content or tissue to insert in the hernia and become twisted or strangulated. Strangulation is a condition in which the circulation to a section of the intestine (or other part of the body) is cut off by compression or constriction; it can cause extreme pain. If the strangulation persists, the tissue can die from lack of blood supply and lead to an infection.
So, in your case, the hernia is not causing you any discomfort, except that it is now protruding more due to your recent weight gain. I would suggest that you leave it alone, and try loosing few pounds, as that will make it invaginate back inside as before. In addition, avoid exert too much forward abdominal pressure with during your routine daily activities. The process of repairing the hernia may involve inserting an artificial inert mesh to hold the abdominal content back. Given that it is not bordering you, and that you have only become concerned since your weight gain, then if you loss some weight and you will be okay. I trust that you will do well.
