10 Medical Diagnoses That Cause Obesity

Abnormal eating patterns and excessive hunger due to genetic mutations

Bardet-Biedl Syndrome

Rare genetic disorder causing obesity, vision loss, and other abnormalities

1 in 140,000 to 1 in 160,000 individuals

Abnormal eating patterns and excessive hunger due to genetic mutations

No cure, but treatment focuses on managing symptoms (e.g., dietary counseling, hormone replacement therapy, and vision aids)

Increased cortisol levels lead to fat deposition, particularly in the face, upper back, and abdomen

Cushing's Syndrome

Excessive levels of cortisol due to adrenal gland dysfunction

Approximately 10-15 cases per million people per year

Increased cortisol levels lead to fat deposition, particularly in the face, upper back, and abdomen

Surgery, radiation, or medications to remove or reduce the source of excess cortisol

Damage to the hypothalamus disrupts appetite and energy balance regulation

Hypothalamic Obesity

Damage to the hypothalamus causing impaired appetite regulation

Rare, depends on the cause of hypothalamic damage

Damage to the hypothalamus disrupts appetite and energy balance regulation

Treatment focuses on addressing the underlying cause (e.g., tumor removal) and managing symptoms through lifestyle interventions and medications

Decreased production of thyroid hormones leads to reduced metabolic rate

Hypothyroidism

Underactive thyroid gland causing slow metabolism

About 4.6% of the U.S. population (12 years and older)

Decreased production of thyroid hormones leads to reduced metabolic rate

Hormone replacement therapy (Levothyroxine)

Excess insulin secretion causes low blood sugar levels, stimulating appetite and weight gain

Insulinoma

Rare pancreatic tumor that secretes excess insulin

1 to 4 cases per million people per year

Excess insulin secretion causes low blood sugar levels, stimulating appetite and weight gain

Surgical removal of the tumor, or in some cases, medications to manage blood sugar levels

Lack of leptin production causes constant hunger and inability to feel full

Leptin Deficiency

Lack of leptin production by fat cells, leading to severe obesity

Extremely rare

Lack of leptin production causes constant hunger and inability to feel full

Leptin replacement therapy (e.g., metreleptin)

Inability of the body to respond to leptin signals, leading to persistent hunger and increased food intake

Leptin Receptor Deficiency

Impaired function of leptin receptors due to genetic mutations

Extremely rare

Inability of the body to respond to leptin signals, leading to persistent hunger and increased food intake

No specific treatment; management focuses on lifestyle interventions, dietary counseling, and weight loss medications

Mutations in the MC4R gene impair appetite regulation and lead to uncontrolled appetite

Melanocortin-4 Receptor (MC4R) Deficiency

Loss of function in MC4R protein involved in appetite regulation

1 in 1,000 to 1 in 1,500 individuals

Mutations in the MC4R gene impair appetite regulation and lead to uncontrolled appetite

No specific treatment; management focuses on lifestyle interventions, dietary counseling, and weight loss medications

Insulin resistance leads to increased insulin production and excess androgen production by ovaries

Polycystic Ovary Syndrome (PCOS)

Hormonal disorder causing insulin resistance, irregular menstrual cycles, and infertility

6-12% of women of reproductive age

Insulin resistance leads to increased insulin production and excess androgen production by ovaries

Lifestyle changes, medications to manage insulin resistance (Metformin), hormonal therapy

Abnormal functioning of the hypothalamus, leading to increased appetite and overeating

Prader-Willi Syndrome

Genetic disorder causing constant hunger, low muscle tone, and developmental disabilities

1 in 10,000 to 1 in 30,000 live births

Abnormal functioning of the hypothalamus, leading to increased appetite and overeating

No cure, but treatment focuses on managing symptoms (e.g., strict dietary supervision, growth hormone therapy, and behavioral therapy)
