Obesity is not a single condition, it is a driver of dozens of conditions that span nearly every organ system in the body. Primary care is the medical setting where most of these conditions are first identified, monitored, and managed. At Dr. Maryam Khan’s practice in Lutherville-Timonium, MD, a patient with obesity is understood to be at risk across a broad clinical landscape, and that comprehensive awareness shapes how Dr. Khan screens, monitors, and treats.
Cardiovascular Disease
Excess adipose tissue, particularly visceral fat, drives a cascade of cardiovascular risk factors:
• Hypertension: Adipose tissue is metabolically active, increasing cardiac output, activating the renin-angiotensin-aldosterone system, and promoting sodium retention. More than 70% of hypertension in the United States is attributable to excess weight.
• Dyslipidemia: Obesity is associated with elevated triglycerides, low HDL cholesterol, and the presence of small dense LDL particles, an atherogenic lipid pattern that accelerates arterial plaque formation.
• Heart failure: Obesity-related cardiac changes include left ventricular hypertrophy and diastolic dysfunction, which increase the risk of heart failure with preserved ejection fraction (HFpEF).
• Atrial fibrillation: Obesity is an independent risk factor for atrial fibrillation through multiple mechanisms including pericardial fat deposition, inflammatory signaling, and left atrial enlargement.
| Even a 5 to 10% reduction in body weight produces clinically meaningful improvements in blood pressure, triglycerides, HDL cholesterol, and insulin sensitivity. These changes occur rapidly, often within weeks of initiating effective weight loss treatment. |
Type 2 Diabetes and Pre-Diabetes
The relationship between obesity and Type 2 diabetes is among the most studied in medicine. Visceral fat drives insulin resistance, the primary metabolic defect in Type 2 diabetes. Weight loss, even modest amounts, improves insulin sensitivity. Significant weight loss (10 to 15% or more) can induce remission of Type 2 diabetes in patients who have had the condition for fewer than five years.
Dr. Khan manages weight alongside diabetes in an integrated fashion, recognizing that GLP-1 receptor agonist medications offer the unique benefit of addressing both conditions simultaneously.
Obstructive Sleep Apnea
Obesity is the dominant modifiable risk factor for obstructive sleep apnea (OSA). Excess fat in the pharyngeal area, combined with reduced lung volume from abdominal adiposity, creates the conditions for upper airway collapse during sleep. OSA in turn worsens insulin resistance, raises blood pressure, contributes to cardiac arrhythmias, and significantly impairs daytime cognitive function.
Weight loss reduces OSA severity in proportion to the amount of weight lost. In some patients with mild to moderate OSA, clinically meaningful weight reduction, particularly with GLP-1 agents, can reduce apnea severity enough to reduce dependence on CPAP therapy.
Non-Alcoholic Fatty Liver Disease (NAFLD)
NAFLD, the accumulation of fat in the liver in patients who drink little or no alcohol, affects an estimated 25% of the global population and is strongly associated with obesity and metabolic syndrome. In its advanced form (NASH, non-alcoholic steatohepatitis), it can progress to cirrhosis and liver failure. There is currently no specific pharmacological treatment for NAFLD/NASH; weight loss is the most effective intervention and is associated with regression of liver fibrosis at sustained reductions of 10% or more of body weight.
Cancer Risk
Obesity increases the risk of at least 13 types of cancer, including endometrial, colorectal, post-menopausal breast, kidney, esophageal, and pancreatic cancer. The mechanisms are multiple: excess estrogen production from adipose tissue, chronic inflammation driven by adipokines, and hyperinsulinemia promoting cell proliferation. Cancer risk reduction is one of the most underappreciated benefits of sustained weight loss.
Musculoskeletal and Joint Health
Each pound of excess body weight translates to approximately four pounds of additional force on the knee joint with each step. Osteoarthritis of the knee, hip, and lower back is significantly accelerated by obesity. Weight loss reduces joint loading and consistently improves pain and function in patients with osteoarthritis, often reducing or eliminating the need for pain medications.
Mental Health
The relationship between obesity and mental health runs in both directions. Depression, anxiety, and low self-esteem are more common in patients with obesity, partly as a consequence of stigma and social effects. Conversely, depression and stress contribute to weight gain through appetite dysregulation, reduced physical activity, and the metabolic effects of elevated cortisol. Effective weight management must acknowledge and address this bidirectional relationship.
Fertility and Reproductive Health
Obesity disrupts the hypothalamic-pituitary-ovarian axis in women, causing menstrual irregularity, anovulation, and reduced fertility. Polycystic ovary syndrome (PCOS) is strongly associated with insulin resistance and obesity. In men, obesity lowers testosterone levels and impairs sperm quality. Weight loss improves fertility outcomes in both men and women with obesity.
Dr. Khan’s Approach to Obesity-Related Risk
Because obesity affects so many organ systems simultaneously, Dr. Khan approaches weight management as an integrated component of overall health care rather than an isolated concern. Each visit assesses the current status of weight-related conditions, updates laboratory monitoring, and adjusts the treatment plan as the clinical picture evolves.
