Seromas occur fairly commonly after abdominoplasty and are usually treated just as your doctor did. The can either be drained with a needle over and over until they go away or a drain can be placed. The very small amount of fluid that your doctor told you would resolve should absorb rather quickly. Occasionally a seroma can be persistent and require other procedures to remove them. 40 days is certainly not in the "unresolving" category. If it does not continue to improve an ultrasound can be done to assess how much, if any, fluid is still present. I would continue to see your doc frequently to keep an eye on this issue. As long as the fluid is not infected (and most seromas are not) it should not be harmful.
