Health Claims

When people take semaglutide 2.4 mg, many feel sick to their stomach, throw up, or have constipation or diarrhea—but very few stop taking it because of these side effects.

Descriptive

When adults with obesity take a drug called semaglutide 2.4 mg for about 1.5 years, nearly 9 out of 10 lose at least 5% of their body weight — compared to only about 1 in 3 to half of those taking a sugar pill or another drug, meaning semaglutide works better for weight loss in most people.

Quantitative

When compared to another weight-loss drug (liraglutide), semaglutide helps people lose nearly twice as much weight—over 70% lose 10% or more of their body weight, while only about 1 in 4 do with liraglutide.

Quantitative

Taking a weekly injection called semaglutide along with healthy eating and exercise can help people with obesity or overweight lose about 15% of their body weight in a year—much more than people who just take a sugar pill.

Causal

In the Middle East, about two out of every three heart attack patients are overweight or obese, which means excess weight is a big problem for this group.

Descriptive

In the Middle East, people who have had a serious heart attack and are overweight are more likely to have another heart problem or bleed badly afterward than those who are a normal weight.

Correlational

In the Middle East, people who are overweight or obese and have a heart attack are more likely to also have diabetes, high blood pressure, or bad cholesterol—but they’re not more likely to die in the hospital than thinner patients.

Correlational

When people stop taking semaglutide, they often gain weight back and feel hungrier — and this might be because their gut bacteria and metabolism go back to how they were before, which could be telling their brain to eat more.

Mechanistic

Even after people stopped taking semaglutide, some of the good effects on fat breakdown in the liver and fat tissue stayed around, likely because certain cellular signals that help burn fat stayed active and others that store fat stayed quiet.

Mechanistic

When people stopped taking semaglutide, their brain started signaling hunger more strongly and fullness less strongly, making them feel hungrier again.

Mechanistic

When women with obesity stopped taking semaglutide, their gut bacteria changed in a way that’s linked to lower levels of a helpful bile acid and reduced activity in a brain region that helps control appetite.

Mechanistic

When women with obesity stopped taking a weight-loss drug called semaglutide after 36 weeks, most of them quickly gained back weight and felt hungrier than before.

Quantitative

Overweight people tend to have worse cholesterol and higher uric acid levels — these might hurt the heart even if they don’t have diabetes or high blood pressure.

Correlational

If you're overweight (BMI 23 or higher) and have kidney disease by itself, it doesn’t really raise your risk of heart problems. But if your kidney disease is caused by high blood pressure or diabetes, then your risk of heart issues goes up a bit.

Correlational

If you're overweight (BMI 23 or higher) and have both diabetes and high blood pressure, these two conditions together are responsible for about 19% of your extra heart disease risk — and they make things much worse when they happen at the same time than if you had just one of them.

Mechanistic

For people who are overweight (BMI 23 or higher), high blood pressure is responsible for about 1 in 5 of the extra heart attack and stroke risk — it’s the second biggest reason after diabetes that extra weight leads to heart problems.

Mechanistic

If you’re overweight (BMI 23 or higher), having type 2 diabetes explains about a quarter of why you’re more likely to have heart problems — meaning diabetes is a big reason why extra weight hurts your heart.

Mechanistic

If you're middle-aged and carry extra weight (even if you're not obese), you're 34% more likely to have a heart attack or stroke over the next 17 years — even if you don’t have diabetes, high blood pressure, or kidney disease. This suggests your extra fat might be harming your heart in ways we don’t fully understand yet.

Correlational

Taking weight-loss medications doesn't seem to help obese adults live longer than those who don't take them — the numbers show no real difference in death rates.

Quantitative

When obese adults take medicines to lose weight, their blood pressure tends to go down a little bit compared to those who take a sugar pill, which might help lower their risk of heart problems.

Causal

When obese adults take weight-loss medications, they tend to lose more weight than those who take a sugar pill, and this difference is real and meaningful.

Causal

When obese adults take medicines designed to help them lose weight, their blood sugar levels go down a little — even if they don’t change how they eat or exercise.

Causal

When obese adults take medicines to lose weight, they’re much less likely to die from heart problems — about half as likely — probably because losing weight helps their blood pressure, sugar, and other heart-related numbers get better.

Causal

Taking a weekly shot called semaglutide 2.4 mg helps people who are overweight and have prediabetes lose a lot of weight—about 15 kg in a year—and even after stopping the shot, they still keep off nearly 9 kg. This also helps stop them from developing full-blown diabetes.
