GLP-1 weight management online in New Jersey and Pennsylvania

What the results actually look like

Real numbers are more useful than promises.

In the main clinical trial of one of these medications, participants lost an average of 17.3 percent of their body weight over 68 weeks. For someone starting at 220 pounds, that is roughly 38 pounds. Trials of the newer dual-acting medications have shown larger average losses.

Two things that average hides:

• Response varies a lot. Some people lose considerably more than the average, and a minority lose very little. There is no way to know in advance which group you are in, and that is worth knowing before you start rather than after three months.
• It is not fast. Meaningful loss takes months, not weeks, partly because the dose has to be increased gradually. Anyone promising rapid results is selling something.

Who should not take these

The list at the top of this page is the short version. In more detail, these medications are not appropriate if you:

• Are pregnant, breastfeeding, or trying to conceive. If you become pregnant on treatment, stop and tell your clinician. If you are planning a pregnancy, these are generally stopped well in advance, and your clinician will tell you how far ahead.
• Have a personal or family history of medullary thyroid cancer, or MEN2. This is an absolute contraindication, not a judgment call.
• Have had pancreatitis.
• Have a history of an eating disorder. A medication that removes hunger cues is genuinely risky in this situation, and declining to prescribe it is us taking that seriously rather than being obstructive.
• Have significant gastrointestinal disease, including conditions affecting stomach emptying.

Tell us about all of these. A medication history and a family history are not box-ticking here.

Side effects, honestly

Most people get some of these. Most are manageable. A few are not, and you need to know which is which.

Common, and usually improving over weeks. Nausea, constipation, diarrhea, vomiting, reflux, burping and reduced appetite to the point of forgetting to eat. These are the price of the mechanism, and they are worst right after starting and right after each dose increase. Smaller meals, eating more slowly and stopping before you are full help more than anything else.

Report these to your clinician. Vomiting that stops you keeping fluids down, which can lead to dehydration and kidney problems. Constipation that is not resolving. Nausea severe enough that you are not eating.

Worth knowing about. Gallbladder problems are more common with rapid weight loss generally, not only with these medications. A small number of people develop significant delays in stomach emptying that persist.

What happens if you stop

This is the most important section on this page and the one most providers leave out.

When you stop, the weight comes back. This is not a willpower failure. The medication replaces a hormonal signal, and when it is withdrawn, the signal goes with it.

The evidence is specific. In the extension of that same trial, participants who stopped the medication after losing an average of 17.3 percent had regained most of it a year later, sitting at 5.6 percent below their starting weight. That is about two-thirds of the loss reversed. The improvements in blood pressure, blood sugar and cholesterol that came with the weight loss largely went back toward where they started as well.

What to take from that:

• Treat this as ongoing treatment, not a course. The closest comparison is blood pressure medication. Nobody expects blood pressure to stay down after stopping a medication that was controlling it.
• Factor the long run into the decision now. Cost, access and whether you can sustain this matters more than the first month’s result. Starting something you will have to stop in four months for financial reasons is a worse plan than not starting.

If you do need to stop, tell your clinician rather than simply stopping. There are ways to make it less abrupt, and a plan for maintaining habits built during treatment gives you a better chance of keeping some of the result.

If you take an oral contraceptive

One of the two main medications used here interferes with oral birth control. By slowing stomach emptying, it affects how the pill is absorbed. The labeling advises switching to a non-oral method, or adding a barrier method, for four weeks after starting the medication and four weeks after each dose increase.

The other main option does not carry the same labeled interaction, but vomiting and diarrhea are common with all of them, and vomiting within a few hours of a pill can mean the dose did not count.

If you use an oral contraceptive, say so at your visit. Switching to a non-oral method removes the problem entirely. See birth control.

What we will not do

Stating this plainly, because the market is full of the opposite.

• We will not prescribe outside the eligibility criteria. If your BMI is below the threshold and you have no qualifying condition, the answer is no. These medications are not a cosmetic product.
• We will not prescribe without follow-up. Dose changes and side effects need a clinician.
• We will not prescribe in pregnancy or to someone trying to conceive.
• We will not skip the history. The contraindications above exist for good reasons.

If the answer is no, you will get an explanation and, where relevant, a pointer toward what would actually help.
