Periodic Limb Movement Disorder (PLMD) is a sleep-related condition that causes repetitive, involuntary leg movements during the night. These movements often disrupt sleep without a person realizing it, leading to daytime fatigue, brain fog, and mood changes.
At SustainMD, we don’t replace neurologists or sleep specialists. Instead, we provide membership-based obesity medicine and primary care that support patients living with PLMD as part of their broader health. This includes considering how sleep quality, hormones, nutrition, medications, and metabolic health factors interact with your symptoms.
Through virtual care with Dr. Allison Pope Barbee, MD, you’ll receive compassionate, personalized support designed to integrate PLMD into your overall health plan — so you feel understood, supported, and cared for over time.
Type of Care: Virtual telemedicine-based memberships
Serving Patients In: California, Florida, Maine, North Carolina
Ideal For: Adults experiencing unexplained fatigue, disrupted sleep, or suspected periodic limb movements
First Step: Initial virtual consultation and assessment with Dr. Allison Barbee
PLMD is often confused with Restless Legs Syndrome (RLS), but the two conditions are distinct. Unlike RLS, which creates an urge to move the legs while awake, PLMD occurs involuntarily during sleep.
Many patients discover PLMD only after a sleep study or because a partner notices the repetitive movements. The result is often poor-quality sleep, leaving patients tired and unfocused during the day.
Low iron or ferritin levels
Chronic conditions such as diabetes, kidney disease, or neuropathy
Sleep disorders, including sleep apnea or insomnia
Hormonal or age-related changes in brain chemistry and sleep regulation
Because PLMD is connected to both sleep and metabolic health, addressing contributing factors like iron status, obesity, and medications is essential.
At SustainMD, Dr. Allison Barbee provides primary care that adapts to patients living with PLMD. Care focuses on identifying contributors, improving energy and sleep quality, and coordinating with specialists when needed.
Review of sleep and health history

Nutrition and lifestyle guidance for better rest
