Direct answer: why Sam Smith gained weight
Sam Smith’s noticeable weight gain is primarily attributed to long-term medication use, including certain antidepressants and anti-migraine drugs, which can affect appetite, metabolism, and fluid balance. Smith has discussed living with conditions such as Graves’ disease and prior vocal cord hemorrhages, which influence energy, voice, and body processes. In interviews, Smith has explained that antidepressants and other treatments changed their eating patterns, led to increased cravings, and slowed weight management. Lifestyle shifts during the pandemic, reduced touring intensity, and a more private routine also contributed. None of these factors tell the whole story on their own, but together they clarify the why behind the change, while Smith emphasizes self-acceptance and body autonomy.
Context and career background
Understanding why Sam Smith gained weight requires placing the change within their career arc. Smith rose to global fame in 2014 with “Stay with Me” and has since navigated major vocal challenges, surgeries, and public health disclosures. Over time, treatments for migraines, mental health conditions, and autoimmune issues introduced physiological changes that affect weight, even when habits seem consistent. Media scrutiny and evolving personal priorities have also shaped how and when Smith performs, travels, and engages with training or diet. As a result, body composition has shifted across albums, award seasons, and periods of rest.
Health conditions and medication effects
Graves’ disease and thyroid function
Graves’ disease, an autoimmune condition that affects the thyroid, can cause changes in energy use, fluid retention, and body composition. When thyroid function is altered, metabolism can slow, making weight gain more likely even if diet and exercise stay the same. Smith has acknowledged living with this diagnosis, which likely contributes to ongoing shifts in weight and energy.
Medications influencing appetite and metabolism
Several of the medications Smith has mentioned—particularly certain antidepressants and anti-migraine drugs—are documented to increase appetite, change food preferences, affect water retention, or slow metabolic rate. For example:
- Some antidepressants are associated with initial weight gain during treatment, partly through increased cravings and changes in how the body stores energy.
- Anti-migraine agents and mood stabilizers can also influence weight by affecting appetite hormones or fluid balance.
Because these medications are tailored to each person’s health profile, responses vary, but the patterns align with explanations Smith has offered about changes in hunger and body shape.
Lifestyle and performance factors
Beyond health conditions and medications, Smith’s lifestyle factors have played a role. During the COVID-19 pandemic, touring paused, training routines adjusted, and daily structure changed, which can lead to weight gain. When performances and travel decrease, individuals often experience reductions in daily step count and physical exertion. Additionally:
- Shifts in meal timing and social eating patterns can affect weight.
- Recovery from vocal cord issues may reduce vigorous activity temporarily.
- Choice to prioritize rest, creative work, and privacy may reshape fitness regimens.
These points explain how someone who once maintained weight through touring can see changes without any single clear cause.
Body positivity and public framing
In multiple statements, Smith has framed their body changes within a broader conversation about self-acceptance and mental health. They’ve emphasized that their worth is not tied to appearance, and they’ve spoken openly about therapy and medication as part of holistic care. From an editorial standpoint, this aligns with body-positive narratives and long-term wellness rather than short-term diet culture expectations. Smith has indicated they eat in ways that support health and comfort, rather than pursuing rapid weight loss.

Summary
Sam Smith’s weight gain is multifactorial, involving medications for depression and migraines, treatment for Graves’ disease, shifts in daily activity due to touring patterns and the pandemic, and evolving personal priorities around rest and mental health. Rather than a single cause, the combination of physiological and lifestyle factors best explains the change. Smith’s openness about therapy, medication, and body image underscores that health and well-being can exist across a range of bodies.
