Aspirin is absorbed both in the stomach and the small intestine , for the former the cause lies beyond the fact that the gastric PH (1.5-2.5) is lower than the pka of aspirin (3.5) such that the ionization of aspirin is so much limited and the unionized and subsequently the lipophilicity of aspirin increases so that it's easily absorbed into the gastric mucosal cells.
for the latter , aspirin absorption is due to the large absorptive surface area of the small intestine despite the fact that the intestinal PH is higher than the pka of aspirin , but still the surface area help absorption of the unionized fraction of aspirin.

Aspirin is an acid with pKa of 3.5 is aspirin more absorbed in stomach where pH is 1 or in small intestine where pH is 6?
Aspirin is absorbed from the stomach but most of it is absorbed from small intestines because of poor dissolution of acidic drug in stomach acid, high dissolution in intestinal contents, large surface area on intestines and good blood flow in intestines

If a patient use aspirin and suffer from stomachaches how can they be cured?
Aspirin can cause an irrated stomach. Ibuprofin (aceteminophen) and bufferin (buffered or coated aspirin) was made primarily to bypass the stomach and be digested in the intestines therefore not irritating the stomach. The heavy use of aspirin can cause ulceritis of the stomach wall and irritate existing ulcers. See the related link for more information.
