Understanding GLP-1 Drugs for Weight Loss and Diabetes

Here I review th GLP-1 drugs, approved for managing type 2 diabetes and aiding weight loss, simulate the GLP-1 hormone, promoting fullness and blood sugar control. While they can be effective, they come with risks and side effects, and long-term success requires lifestyle changes, regular exercise, and mental health support, as emphasized by healthcare professionals.

This information is current as of the date of original publication or update but may have changed by the time you read this. Do not use this information for diagnosis or treatment purposes. Before making health decisions, discuss with a qualified healthcare professional.

When I was in medical practice, patients asked me for weight loss drugs. There were a few that varied in effectiveness, side effects, and risks. In general, none were effective in significant long-term weight loss.

I also had numerous patients with type 2 diabetes who needed medication to achieve optimal blood sugar levels, but did not want or need insulin. Again, there were several, but most patients needed at least two drugs to lower the glucose to the target level.

Then came the GLP-1 drugs.

GLP-1 medications (glucagon-like peptide-1 receptor agonists) are FDA-approved drugs used to manage type 2 diabetes and chronic weight loss. Popular brands include Wegovy, Ozempic, Mounjaro, and Zepbound, which are generally meant for adults with high BMI (body mass index) or weight-related conditions. 

(Body Mass Index (BMI) is a screening tool that calculates a person’s body fat percentage based on their height and weight. It is calculated by dividing weight in kilograms (kg) by height in meters squared.)

How GLP-1 Drugs Work

  • Appetite Regulation: They mimic the GLP-1 hormone, signaling to the brain that you are full, reducing hunger and calorie intake.
  • Blood Sugar Control: They stimulate insulin release after meals and prevent the liver from producing too much glucose.
  • Slower Digestion: They delay gastric emptying, keeping food in the stomach

However, they are not perfect and have risks.

  • Possible side effects -nausea, vomiting, diarrhea, constipation, and abdominal pain, which often improve over time.
  • Potential for thyroid C-cell tumors (based on animal studies), pancreatitis, kidney issues, and severe gallbladder issues.
  •  Rapid weight loss can cause “GLP-1 face” (loss of facial fat leading to a sagging/wrinkled appearance)
  • costs over $1000 per month, and insurance coverage varies
  • FDA has warned about risks associated with unapproved, compounded versions of these medications.

Taking a GLP-1? Doctors Say Not To Forget About Movement and Mental Health

Severe ankle pain drove Jelon Smart to start taking a weight-loss injection a year and a half ago.

Smart was 285 pounds and worked as a caterer in Savannah, Georgia. After she’d been standing on her feet for long hours, her ankles would be “as swollen as a football,” she said. She was walking with a limp.

An orthopedic doctor diagnosed her with Achilles tendinitis and recommended losing weight to mitigate the symptoms. Smart began taking the brand-name GLP-1 Ozempic.

The appetite suppression resulted in her shedding pounds quickly, at first.

“I lost 30 pounds initially without changing anything,” said Smart, 48. But then she found herself unable to shed additional pounds.

GLP-1 Drugs- Weight Loss Made Easy

GLP-1s have quickly become one of the most popular types of weight loss drug in America. Nearly 1 in 5 people have taken them at some point, according to research from KFF, a health information nonprofit that includes KFF Health News.

But doctors say it takes more than a regular shot for patients to achieve their weight goals in the long run.

Here’s what to know.

The Old-School Rules of Diet and Exercise

Regular exercise, smart food choices, plenty of sleep — those basic, healthy lifestyle choices are not only going to help you lose weight on a weight loss drug but also help you keep it off, said Dafina Allen, an  obesity medicine physician who runs a clinic in Saginaw, Michigan.

For example, some people find that they eat less on a GLP-1, “but they’re not improving their health because they’re not exercising. They’re not improving the quality of the food they’re eating,” Allen said.

The path to weight loss is also guided by hormones, metabolism, and genetics.

After her weight loss on Ozempic plateaued, Smart realized she needed to start moving her body, too.  “I’m in the gym now six days a week,” she said. “I went from 285 to 175” pounds. The swelling and pain in her ankle went away as well.

Mental Health Matters Too

The mind and body are deeply connected. Food and body image can be especially emotional, Allen said. “I can tell you about the patients that I helped lose 50 pounds, that I helped lose 100 pounds, and they still look in the mirror and are not happy.”

The key is seeking help for mental health along the way, said Gerald Onuoha, who practices internal medicine in Nashville, Tennessee. “Making sure that you’re talking to people about your problems, whether it’s a family member or a licensed professional, I think goes a long way,” he said.

Work With a Doctor To Closely Monitor Your Dosage

Onuoha said people can run into serious problems if they increase their GLP-1 dosage too quickly or don’t follow the recommended schedule. He’s seen patients come to the hospital with pancreatitis, gallstones, or acute kidney injury.

 “I always ask patients who are on GLP-1s: How long have they been on them?” he said. “Are they adhering to the directions? Because those things determine whether or not you’re going to have those complications.”

Part of the issue, Allen said, is that GLP-1s are relatively easy to access — and often much cheaper — through online pharmacies or websites, but those providers may not educate patients about their dosage or side effects.

“So they might just go online, find a random company that will ship it to their house, where they don’t even know what dose of the medication they’re taking, or even if the medicine is safe for them as the patient with the medical conditions they have,” she said.

People and Policy-Who Pays for GLP-1s?

GLP-1 drugs can be costly, and most insurance programs — public or private — don’t cover the medications for weight loss.

Medicaid, the government program that covers 69 million Americans, covers GLP-1s for medically accepted conditions like diabetes, but only about a dozen state Medicaid programs cover GLP-1s for obesity treatment, according to KFF.

For older Americans with Medicare, the federal government is planning to allow temporary coverage of GLP-1s for weight loss starting in July.

How 99 Ways to Die Might Save Your Life-a book review

In this post I review “99 Ways to Die and How to Avoid Them.” Dr. Ashely Alker, an emergency physician, humorously outlines various health risks and preventive measures. Combining personal anecdotes with medical insights, she emphasizes the importance of awareness in avoiding fatal incidents and advises readers to prioritize health habits over misinformation, and seeking medical care as soon as possible.

99 Ways to Die

And How to Avoid Them

by Ashely Alker, M.D.

Published January 2026 by St. Martin’s Press

Thank you, NetGalley and publisher, for sending this book for review consideration.

Why would a medical doctor write about ways to die? Aren’t they supposed to keep people alive?

Yes, and that’s why Dr. Ashely Alker, a “death escapologist”, wrote 99 Ways to Die. As an emergency medicine specialist, she says this book is bad for business. Reading it, and following her advice, may keep you out of her emergency room. Better yet, it may save your life.

Dr. Adler briefly shares her pre-medical life and education, including overseas study for a master’s degree in public health. She relates personal experiences with illness and the healthcare system, which led her to medical school and residency.

The table of contents reads like a textbook of emergency medicine, in that it includes both illnesses and situations that can lead to illness. Some of them you have no doubt heard of.

  • Heart Attacks
  • Cancer
  • Ebola virus
  • Nuclear blast radiation

But have you heard of

  • Schistosomiasis,
  • Mad Cow disease,
  • Venomous agent X,
  • Takotsubo cardiomyopathy

And you’ve heard of but may not believe can be deadly.

  • Influenza,
  • Measles,
  • High Blood Pressure,
  • Pregnancy,
  • Health Influencers (yes, she really wrote this)

She devotes ample discussion to infections, both bacteria, viral, fungi, and even parasites. One whole chapter is on vaccine-preventable infections (obviously, she advocates vaccination)

One of the top five frequent causes of death is accidental trauma, which is often overlooked in discussions of preventive medicine. Not Dr. Adler. She details the ways things like drugs, animals, vehicle crashes, crime, sports, weather, and war can harm and kill us. And don’t forget the dangers of food and water!

You may be thinking this book must be highly technical. She does use scientific names and terms, which she explains in simple language. Her tone is engaging and conversational. She is blunt, sometimes humorous, but always perfectly serious.

She shares stories of her own patients with these conditions; details changed for privacy. Is some of it gory or scary? Maybe, depending on your comfort level and how much you want to know about the human body and how it can be misused and abused.

Disease and death affect all of life and history, as she points out in discussing the impact of the influenza epidemic of 1918 and the COVID-19 pandemic of 2020. I found her discussion of the atomic bombs dropped on Hiroshima and Nagasaki, Japan in World War II particularly poignant.

The initial blasts killed over 200,000 civilians, with many more dying later from radiation illness. In her review of biological and chemical warfare, she suggests we consider carefully who we put into power.

 From this book, you will learn that health is more than knowing your blood pressure and cholesterol. Our risk of disease is more due to where and how we live, and our socioeconomic status. The most important number for your health may be your zip code in the United States.

None of us expect to die from an automobile collision, hypothermia, homicide, drowning, tornado, poisoning, insect bite, or war, but we might and she explains how to avoid it. Common sense things-wear a seat belt, dress for the weather, apply insect repellent, don’t believe medical misinformation you read online. Learn CPR and save someone else’s life.

I’m a physician and worked in ERs, but I still learned from her book. So, I believe you will also. Her main takeaway is to value and care for your body, you only have one. As she wrote in her dedication

May we all be alive this time next year.

Dr. Ashely Alker
