The smallest sign of weight regain is easy to miss. It can be a slightly tighter waistband, a change in how hungry you feel, or a number on the scale that has moved a little each week. The goal is to catch that trend early, and to ask the right questions before a medicine ends.
Before treatment ends
Ask what the plan is
Ask your provider what happens when a medicine stops. Will it be stopped at once or reduced? Will you be checked afterward, and when? NIDDK's page on prescription medications to treat overweight and obesity is a plain place to read how these medicines are described.
Write down your starting point
Record your weight, your usual appetite and your daily habits on the day the medicine ends. Later changes only mean something against a starting point.
After treatment ends
Track weight the same way each week
Weigh at the same time of day, under the same conditions, and write it down. One reading means little. A direction over several weeks is what to bring to a visit.
Track appetite and routine
Note changes in hunger, meal size, sleep and activity. If weight and appetite move together, say so.
Why a long view helps
Ask your provider how long they expect to follow your weight. To see how the condition itself is described, read NIDDK's page on adult overweight and obesity. For background on how medicines for chronic weight management reach the public, see an FDA announcement of a new medication for chronic weight management.

Acting on a steady trend
Do not wait for a large change. Set a starting point, track weekly, and contact your provider when you see a steady trend. Public health pages do not predict what will happen to your own weight after treatment, and a weekly log cannot either.
