The Medical Reality: How Lupus Medication Causes Weight Fluctuation

The primary, non-negotiable reason behind Selena Gomez’s body changes is her health management plan for Lupus. Systemic Lupus Erythematosus (SLE) is a chronic autoimmune disease where the body's immune system attacks its own tissues and organs.

1. The Side Effects of Lupus Medication (Steroids)

The most common and effective treatment for managing lupus flare-ups and organ damage, especially post-kidney transplant, involves corticosteroids, often referred to as steroids. These medications are life-saving, but they come with significant, well-documented side effects that directly impact body weight and appearance. * Water Retention: Steroids cause the body to retain fluids, leading to rapid and noticeable swelling, particularly in the face (known as "moon face") and abdomen. This is a common form of *steroid-induced weight gain*. * Increased Appetite: Corticosteroids stimulate appetite, making it challenging for patients to maintain a consistent diet. * Fat Redistribution: The medication can cause fat to be deposited in specific areas, such as the face, neck, and upper back, which alters a person's shape irrespective of their overall body fat percentage. Selena has been candid about this, stating that when she is taking her lupus medication, she tends to gain weight, and when she is off it, she loses it. Her choice is simple: prioritize feeling well over fitting a societal beauty standard.

2. The Kidney Transplant and Ongoing Management

Selena Gomez underwent a life-saving kidney transplant in 2017 due to complications from her lupus. Following a major organ transplant, a patient must take immunosuppressant drugs for the rest of their life to prevent the body from rejecting the new organ. These powerful medications, while essential for survival, can also affect metabolism and contribute to a fluctuating body weight. It is a complex, delicate medical balancing act that far outweighs the public's superficial scrutiny.

Selena's Powerful Response to Body Shaming and 2025 Triumph

Instead of hiding from the cruel comments, Selena has consistently used them as an opportunity to educate and advocate, turning her personal struggle into a global message of body positivity and self-acceptance.

3. "I'm Not a Model. Never Gonna Be."

Selena’s most viral clapback came during a TikTok livestream where she directly addressed the comments about her body. She stated firmly that the weight gain was due to her lupus medication, adding: "I just want people to know that you're beautiful, and you're amazing. Yeah, we have days where maybe we feel like s***, but I would rather be healthy and take my medications, and my body is just not a model's body, never gonna be." This statement became an anthem for those struggling with chronic illness and body image issues.

4. The Gendered Double Standard

She has also highlighted the gendered double standard in the media, noting the intense scrutiny placed on women's bodies compared to men's. Her consistent message, reinforced through her Rare Impact Fund initiatives, is that focusing on mental health and self-love is infinitely more important than chasing an unrealistic aesthetic. By openly discussing her struggles with anxiety and depression, she has decoupled her self-worth from her physical appearance.

The 2025 Body Transformation: Health and Non-Restrictive Living

The narrative around Selena Gomez’s body took a new turn in late 2024 and early 2025. Following a period of noticeable weight gain due to medication, her appearances at events like the 2025 Golden Globes and SAG Awards sparked intense public discussion about a significant weight change.

5. A Focus on Health, Not Dieting

Reports in early 2025 suggested a substantial body change, with some sources claiming a loss of around 30 to 40 pounds from her peak weight in the previous year. Crucially, this transformation was not attributed to restrictive celebrity dieting but to a sustained, non-restrictive approach to health. * Non-Restrictive Fitness: Her personal trainer has emphasized that Selena does not weigh herself, follow strict diets, or focus on rigid food rules. The focus is on consistency, sustainable movement, and a balanced diet that supports her complex health needs. * Mental Well-being First: The success of her Rare Beauty brand and the launch of the Rare Impact Fund have positioned her as a mental health advocate. Her physical health journey is intrinsically linked to her mental well-being, proving that a holistic approach is the most effective and sustainable. * The Power of Advocacy: By sharing her truth, Selena Gomez has not only protected herself from the worst of the body shaming but has also created a powerful platform for others. Her journey—from a teenage star to a powerful businesswoman battling a chronic illness—epitomizes resilience and a refusal to let external judgment define her value. Her 2025 body positivity triumph is a victory for health and self-love over superficial standards.
