Zahid Ahmad, M.D.
- Internal Medicine - Endocrinology
Zahid Ahmad, M.D., is an Associate Professor in the Division of Endocrinology at UT Southwestern Medical Center.
Dr. Ahmad’s clinical and investigative focus is lipid metabolism disorders, including dyslipidemia, chylomicronemia, and familial hypercholesterolemia (FH).
His research aims to identify the causes of cholesterol and triglyceride disorders and to develop new treatment options for patients who suffer from them.
Funded by the National Institutes of Health, Dr. Ahmad and his colleagues currently are working to identify families with these conditions in an effort to better understand their underlying genetic causes – and, ultimately, to improve patient outcomes.
Dr. Ahmad has published a number of scholarly articles and delivered many invited lectures.
He joined the UT Southwestern faculty in 2010 and is American Board of Internal Medicine-certified in internal medicine, endocrinology, metabolism, and diabetes.
Dr. Ahmad earned his medical degree at the Tulane University School of Medicine.
He completed both a residency (internal medicine) and a fellowship (endocrinology and metabolism) at UT Southwestern Medical Center – training in cholesterol metabolism and genetics with mentors Drs. Abhimanyu Garg, Scott Grundy, and Helen Hobbs.
He also holds a B.S. in biomedical engineering from the Tulane University School of Engineering.
Active in the FH Foundation, Dr. Ahmad also is a member of professional organizations that include the American Heart Association, Endocrine Society, National Lipid Association, and American Association of Clinical Endocrinologists.
In 2019, Dr. Ahmad was named a Texas Monthly Super Doctor Rising Star.

Dallas Endocrinologist Specializing in Lipid Disorders
In both the clinic and the lab, Zahid Ahmad, M.D., is working to fight lipid metabolism disorders – abnormalities in the way the body processes cholesterol and fat.
An endocrinologist at UT Southwestern Medical Center, Dr. Ahmad specializes in treating patients with extremely high levels of LDL cholesterol and triglycerides.
These patients include those with conditions such as dyslipidemia, chylomicronemia, and familial hypercholesterolemia, a genetic condition that causes LDL cholesterol to soar to dangerously high levels.
Dr. Ahmad also has special expertise in treating patients unable to tolerate their cholesterol medications – an issue that affects up to 10 percent of patients prescribed these drugs.
“I’m motivated by helping people who no one else has been able to help, both in the clinic and through my research,” he says. “Our clinic is a referral center for the most complex patients – those experiencing the most problems with their lipid levels and their medications.”
Active in investigating lipid disorders, Dr. Ahmad continues to build upon UT Southwestern’s Nobel Prize-winning discoveries in the field.
“Conducting research gives me a lot of insight into all the different cholesterol and triglyceride drugs, and it keeps me current on the most promising practices and ways of managing lipid disorders,” he says. “It also helps me facilitate patient enrollment in clinical trials of new, leading-edge medications.”
Dr. Ahmad was attracted to endocrinology because he has many family members who suffer from diabetes and early-onset cardiovascular disease.
“That led me to really specialize and develop a niche in treating and investigating cholesterol and triglyceride issues.”
Dr. Ahmad is fellowship trained and certified by the American Board of Internal Medicine in internal medicine, endocrinology, metabolism, and diabetes.
