What Causes Weight Gain?
Last reviewed: May 2026 · Haute MD Editorial Team
Weight gain occurs when caloric intake consistently exceeds caloric expenditure — but this oversimplifies a complex process. Drivers include insulin resistance, elevated cortisol, hypothyroidism, low testosterone, PCOS, sleep deprivation, ultra-processed food consumption, certain medications, gut microbiome dysbiosis, and genetic predisposition accounting for 40-70% of obesity risk.

When to seek physician guidance
A board-certified physician can evaluate your individual metabolic profile, hormonal status, medications, and lifestyle factors to design a personalized treatment plan. Comprehensive evaluation typically includes blood work, body composition analysis, and a detailed history before initiating any pharmacological or structured intervention.
Frequently Asked Questions
Who is this most relevant for?
Adults with weight-related health concerns, metabolic dysfunction, or those who have struggled to achieve sustainable weight loss through lifestyle changes alone. A physician evaluation determines individual suitability.
Is treatment covered by insurance?
Coverage varies widely. Some insurance plans cover obesity treatment, GLP-1 medications, and metabolic evaluations when medically indicated, while others do not. Verify benefits with your insurer and the physician's office in advance.
What is the first step?
Schedule a comprehensive consultation with a board-certified physician experienced in weight management. Expect a detailed medical history, physical examination, lab work, and discussion of your goals before any treatment plan is finalized.
