What causes weight gain?

Weight gain is usually multifactorial. Energy balance matters, but hormones, insulin, thyroid function, medications, sleep, stress and genetics all influence appetite, metabolism and where fat is stored.

A single cause is rarely the whole story, which is why evaluation looks at the full picture.

Common concerns

People often notice gradual weight gain despite unchanged habits, weight that concentrates around the middle, difficulty losing weight with diet and exercise, or weight gain alongside fatigue, mood or hormone symptoms.

These patterns can point toward metabolic or hormonal factors worth evaluating.

Possible causes

Contributing factors can include insulin resistance, thyroid conditions, hormone changes such as perimenopause or low testosterone, medications, poor sleep, chronic stress, and changes in activity or diet.

Identifying which factors apply to you guides both evaluation and treatment.

How it is evaluated

Evaluation includes a detailed history, medication review and labs: thyroid panel, fasting glucose, A1C, fasting insulin, lipids, liver enzymes and hormone markers as appropriate.

Labs are completed near you or with home kits where available, depending on your state and the tests ordered.

Care options that may be considered through telehealth

Depending on findings, care may include nutrition and lifestyle planning, sleep and stress support, thyroid or hormone management, and, when appropriate after evaluation, medications such as GLP-1 receptor agonists.

The plan is individualized, monitored and adjusted over time.

Lifestyle factors

Protein and fiber, regular activity including strength training, consistent sleep, stress management and mindful eating habits are the foundation. The plan makes these realistic and sustainable rather than prescriptive.

When to seek urgent care

Weight gain is not an emergency, and telehealth is not for emergencies. Rapid weight gain with shortness of breath, leg swelling or chest pain can signal a serious problem and warrants immediate care: call 911 or go to the emergency room.

Weight Gain FAQ

Why am I gaining weight?

Weight gain is usually multifactorial and can involve hormones, insulin resistance, thyroid function, medications, sleep, stress and lifestyle. Evaluation helps identify the factors that apply to you.

Is my weight gain hormonal?

Hormone changes such as perimenopause, low testosterone or thyroid conditions can contribute to weight gain. Labs help determine whether hormones are part of the picture.

Can thyroid problems cause weight gain?

Yes. Hypothyroidism slows metabolism and can contribute to weight gain, though weight changes are multifactorial and treatment alone does not always reverse them.

Can medications cause weight gain?

Yes. Some medications affect appetite, metabolism or fluid balance. Your medication list is reviewed as part of the evaluation, and changes are only made with your prescribing clinician.

Does stress cause weight gain?

Chronic stress raises cortisol, which can increase appetite, cravings and abdominal fat storage. Stress management is part of most weight plans.

Does sleep affect weight?

Yes. Poor sleep disrupts appetite-regulating hormones and can increase cravings and calorie intake. Improving sleep is a core part of the plan.

How is weight gain evaluated?

Evaluation includes a detailed history, medication review and labs such as thyroid panel, glucose, A1C, insulin, lipids, liver enzymes and hormone markers as appropriate.

What labs are used?

Testing may include thyroid panel, fasting glucose, A1C, fasting insulin, lipids, liver enzymes and hormone markers, chosen based on your history and symptoms.

What treatments are available?

Depending on findings, care may include nutrition and lifestyle planning, thyroid or hormone management, and medications such as GLP-1 receptor agonists when appropriate after evaluation.

Are GLP-1 medications an option?

GLP-1 receptor agonists may be considered when appropriate after evaluation, as one part of a broader plan that includes nutrition and lifestyle support.

How is progress monitored?

Follow-up visits track weight, body composition, labs and symptoms, and the plan is adjusted based on your response and clinical judgment.

Can weight concerns be evaluated by telehealth?

Yes. Evaluation, labs and coaching work well by video visit, in states where Dr. Miklos Major II, Sc.D., DNP, NP-BC, FAAMFM holds an active license.
