He took Ozempic to manage diabetes. Months later, he says he lost his vision -- and his job. Now he's suing over what he alleges happened.
Sen. Mark Warner announced that his daughter Madison has died following a "decades-long battle with juvenile diabetes and other health issues." She was 36.
"We are heartbroken beyond words over the passing of our beloved daughter," Warner and his wife Lisa Collins said in a statement posted on the senator's Instagram Monday. "She filled our lives with love and laughter, and her absence leaves an immeasurable void."
Juvenile diabetes - now more commonly known as Type 1 diabetes, per Mayo Clinic - is a chronic health condition affecting 2.1 million Americans, according to a 2026 report from the Centers for Disease Control and Prevention. About 314,000 of those diagnosed are children or adolescents younger than 20.
Here's what to know about both Type 1 and Type 2 diabetes.
What is Type 1 diabetes?
Diabetes is a chronic health condition. With Type 1 diabetes, the body can't produce enough insulin and with Type 2 diabetes, it doesn't use it properly.
Type 1 diabetes is an autoimmune disease that prevents the body from producing enough insulin. In patients with Type 1 diabetes, beta cells, a hormone located in the pancreas that creates insulin, are destroyed. This destruction may happen quickly or over time until a critical mass of beta cells is lost, leaving the individual unable to survive without insulin from external sources. This is why many people with Type 1 diabetes undergo regular insulin injections.
Who is at risk for Type 1 diabetes?
According to Mayo Clinic, symptoms for Type 1 diabetes can come on suddenly and include the following: feeling thirstier than usual, urinating frequently, wetting the bed, feeling very hungry, losing weight without trying, feeling irritable or having other mood changes, feeling very tired or weak and having blurry vision. Risk factors include family history, genetics and geography, with more people diagnosed with Type 1 diabetes in areas further from the equator.
Age is also a factor. The condition more frequently appears between ages 4-7 and 10-14. However, Type 1 diabetes can still occur at any age. Some patients have been diagnosed in their mid-60s, and data suggest more than half of new Type 1 cases occur in adulthood, Dr. Rodica Busui, professor of medicine at the Oregon Health and Science University's division of endocrinology, diabetes and clinical nutrition, previously told USA TODAY.
What is Type 2 diabetes?
Type 2 diabetes is the more common form of diabetes. In Type 2, beta cell dysfunction has multiple, complex causes, including weight gain, lifestyle changes and lack of exercise. Family history, ethnicity and age can also play a role.
These changes cause the body to stop using insulin properly. This is called insulin resistance, and it makes it harder to bring blood glucose levels down. This can cause changes in the brain and warp your sense of satiety, or how full you are.
How is Type 2 diabetes treated?
In cases of Type 2 diabetes, early diagnosis is key and can help patients make lifestyle changes or start on medication to prevent further complications. These lifestyle changes can include healthy eating, regular exercise, weight loss, and medication or insulin therapy to help keep blood sugar levels in a healthy range.
If patients ignore high blood glucose levels, "the higher blood glucose then generates some changes in the body metabolism that will lead to all these toxic radicals that actually have an additional effect on the beta cells to make them less and less functional," Busui previously told USA TODAY.
