Obesity and hypertension: Researchers discover novel mechanisms
Hypertension is a widespread comorbidity of patients with obesity that greatly increases the risk of mortality and disability. In recent years, researchers have found that a high-calorie diet increases the density of blood vessels (hypervascularization) in the hypothalamus — an important “eating control” area in our brain. Researchers hypothesized that elevated hormone levels of leptin […]
