Hypothyroidism – Virtual Membership-Based Primary Care That Supports Thyroid Health
Fatigue, weight changes, mood shifts, and brain fog are common struggles for people living with hypothyroidism and Hashimoto’s thyroiditis. These conditions affect the thyroid’s ability to regulate metabolism, energy, and hormones — which can disrupt daily life in significant ways.
At SustainMD, we understand how thyroid imbalances connect with weight, energy, and overall metabolic health. Dr. Allison Barbee provides obesity medicine and primary care that adapts to your thyroid condition, while coordinating with specialists when needed. Our membership model ensures continuous, personalized support — not just a one-time prescription.

Recognizing Symptoms and Challenges
Common Signs of Hypothyroidism
Persistent fatigue or low energy
Weight gain or difficulty losing weight
Sensitivity to cold
Hair thinning or hair loss
Constipation and digestive changes
Dry skin or brittle nails
Brain fog, memory problems, or depression
Irregular or heavy menstrual cycles
Causes and Links to Metabolic Health
Factors That Can Worsen Symptoms
Nutrient deficiencies (iron, vitamin D, selenium)
Chronic stress or poor sleep
Weight changes or metabolic dysfunction
Medications or autoimmune overlap
Hashimoto’s thyroiditis is an autoimmune condition where the immune system attacks the thyroid, leading to underproduction of hormones. This affects not only energy and mood, but also weight and metabolic balance.
