How long does it take to see results from lipo? I had it 2 weeks ago and so far I feel like more could have been taken out.

Swelling can sizable he camouflage results of liposuction but most patients see some improvement immediately. By six weeks about 75% of the swelling is resolved. The final resolution may take a number of months.

This is nothing
to worry about, especially two weeks in. As long as your pain is manageable,
and there have been no other complications, the way your body looks after
surgery can only improve. Swelling may be contributing to your dissatisfaction
with the results, and it should continue to decrease noticeably through the
first four weeks. You should be able to judge the final results by six months
and should discuss with your surgeon whether another procedure to revise the
original is needed to attain your desired look.

In the first month the swelling diminishes around 50%, 75% in the second month and 90% in the thirty month, so you'll be able to see the final results in about 3 months from the surgery.

Some patients see more immediate results than others. The swelling needs to resolve and this requires patience on your part. If you do not see a noticeable improvement after three months, then discussion with your plastic surgeon would be appropriate. 

Liposuction patients need to be patient.  Maximum swelling usually occurs in the first 5 days then slowly resolves.  Usually at 3 weeks most patient see a good improvement but there is usually about 30% swelling at that point.  Final results typically take 6 months to achieve.  Follow all instructions for your best result.
