Your curve has developed over time and is called a hyperlordosis at this point. If your stomach is sticking out, it is most likely caused by this excess curve. You can do curve restoration exercises with a rehab based chiropractor or physical therapist to help reduce it. Age will matter in terms of changing the curve fully, but there is still some change that will occur over time.

Most likely, aging is the problem with the body distortion. However, if there is discomfort, chiropractic care may give relief rather that allowing it to get worse.
Will it get to completely straight or completely normal at this point? Most likely not. Find a great doctor who will take films and analyze and measure as well as work you up a plan of correcting the problem over time. If your problem started at birth, then you would be looking at approx. 6 years of care to get it to your best - whatever that can be for you.
