‘Well with Arielle’ Breaks Down the Top Hormone Myths About Weight Gain, Hair Loss, Acne and More

Hormone talk online is loud, and it’s often wrong. On Well with Arielle Lorre, she brings back Dr. Jordan Geller—a dual board-certified physician who’s seen how fast misinformation turns into expensive labs, unnecessary meds, and a whole lot of self-diagnosing. His promise is simple: “It is not typical wellness fear mongering, it’s really just clear science-backed information to help you cut through the noise.”

Myth #1: Birth control is a harmless hormone fix

Geller is clear that this is the biggest hormone myth he sees—especially for women who were put on the pill young and stayed on it for years without much discussion. His core issue isn’t that birth control is never appropriate, but how casually it’s prescribed. As he explains, “a lot of young women get put on birth control for non-contraceptive purposes,” often for acne, irregular periods, or mood, “with zero discussion from a physician about…side effects.”

One of the most persistent misconceptions is that birth control “balances” hormones. What it actually does is suppress them. “All it’s just doing is it’ll suppress your own hormones,” Geller says. That means hormone testing while on the pill doesn’t reflect your body’s natural baseline, and symptoms can get masked rather than resolved.

He also doesn’t sugarcoat potential downsides, from mood changes to nutrient depletion to sexual side effects. “I’ve seen this like thousands of times in my practice,” he says, adding that many patients are angry they were never informed. 

Myth #2: Your thyroid is always the culprit

When symptoms stack up—fatigue, weight changes, hair issues—it’s easy to land on one explanation. Geller says the thyroid gets blamed most often because “thyroid hormone affects every system in the body, like our brain energy, our mood, our heartbeat, our digestion, skin, hair, nails, menstrual cycles, digestive health.” With a role that big, it becomes the default answer.

What he sees in practice is different. Patients arrive convinced—“I know it’s my thyroid”—and the labs come back normal. That’s where frustration sets in, but he’s clear the goal isn’t to stop there. “My approach in that scenario is not to leave someone feeling stranded. I always want to at least help direct them in the right way.”

Geller also cautions against obsessing over one number. There’s “the normal range, and then there’s the optimal range,” and context matters. Add in factors like stress, restrictive dieting, or medications, thyroid labs can shift without being the root problem.

Myth 3: GLP-1 medications are a simple, one-and-done fix

GLP-1s might be the loudest hormone conversation online right now, which is exactly why Geller flags them as one of the most misunderstood. Early on, he makes it clear the confusion starts with expectations. “Almost anybody is going to be able to lose weight on a GLP,” he says. “The challenge is maintaining it in a safe way and ultimately hopefully getting off the GLP.”

His framing is blunt, but real: “It’s the maintenance, not the victory.” The medication can be effective, but it doesn’t replace nutrition, muscle preservation, or long-term habits. Where things go sideways, he explains, is when people starve themselves, lose weight quickly, and skip the foundational work. When they stop the drug, “the metabolism is just gonna crash.”

He’s also concerned about how casually these medications are accessed. Compounded versions, online purchases, and poor monitoring create real risk. “There’s no regulation…there’s no FDA…there’s been tons of cases of hospitalizations,” he warns, pointing to dosing errors, contamination, and severe side effects.

Myth #4: Growth hormone is a longevity shortcut

Growth hormone has become one of the most misleading status symbols in modern wellness. Longevity clinics and anti-aging centers sell it as a way to stay lean, youthful, and biologically young—but Geller shuts that down fast. “It’s not a longevity drug,” he says, and the science backs him up.

In fact, he explains that research shows the opposite pattern: “the higher people’s growth hormones, the shorter their lifespan.” One of the clearest examples comes from populations with genetic growth hormone mutations. “They’re super short,” he notes, but “they live an extremely long life.” That alone pokes a major hole in the anti-aging narrative.

Growth hormone can change how you look. Geller acknowledges it may improve “lean body mass and bone density and skin,” which is why it’s appealing. But those cosmetic benefits come with trade-offs. “It can cause cancer to grow,” he also warns, calling it “like fertilizer to a cancer cell.” It’s also linked to insulin resistance, diabetes risk, joint pain, and carpal tunnel.

There is a legitimate role for growth hormone—people with true deficiencies, pituitary disease, or specific medical conditions. Outside of that context, using it for longevity is a gamble.

Myth #5: Bone density is only an older person’s problem

Bone health tends to get filed under “deal with it later,” but Geller says that’s a mistake with long-term consequences. Osteoporosis may show up later in life, but the groundwork is laid much earlier. “Everything that people are doing in their childhood years, their teens, their 20s, up to 30, that’s where we really reach our peak bone mass by about age 30.”

That’s why bone loss can quietly start decades before anyone is paying attention. It’s also why osteoporosis is “a silent disease.” As Geller explains, “You don’t feel it, you don’t know it until you have an unusual fracture,” sometimes from something as minor as a fall, a hug, or even a deep tissue massage.

He sees low bone density in younger people more often than you’d expect, especially those with inflammatory bowel disease, eating disorders, missed periods, or low testosterone. Menopause accelerates the issue too. Without estrogen, women can lose “about six percent of their bone mass in a year” early on, which adds up fast. That’s where daily habits matter more than people think. Adequate protein, calcium, minerals, and resistance-based movement all support bone strength. 

Myth #6: Biotin is the answer to hair loss

Biotin might be the most overhyped supplement in the hair loss conversation. “Biotin also actually has very, very little evidence of being beneficial for hair loss,” Geller claims, except in people who are truly deficient—which he notes is rare in developed countries.

What makes biotin more problematic isn’t just that it doesn’t do much. It can actively confuse the picture. “It interferes with the accuracy of hormone testing,” he explains, because “they actually use biotin in the lab to help measure thyroid hormone.” High doses can skew results, which is why he recommends stopping biotin for a few days before hormone labs. Otherwise, you might end up chasing a problem that isn’t really there.

So what does matter for hair? Geller keeps coming back to basics. “Protein.” If intake is too low, “our body’s going to allocate the protein for your heart and your liver and your bones,” and “skin, hair, and nails will be shortchanged.” He’s seeing this more now, especially in people on GLP-1s who aren’t eating enough.

Myth #7: You can cure any hormone issue naturally

Geller states that the idea that every hormone problem can be cured outside of medicine ignores how serious some conditions actually are. “I’m not here to badmouth naturopaths,” he says, and he makes it clear he believes in integrative care. But he’s also seen what happens when medical workups get skipped. “I’ve seen some scary things where people have…a medical adrenal disorder, and they almost died because they were under the care of a naturopath who missed it.” The same goes for pituitary disorders and other endocrine conditions that require proper diagnosis and monitoring.

Hormone symptoms can overlap with stress, under-eating, or burnout—but they can also signal something structural or life-threatening. “There’s a way that we do this stuff in medicine,” he explains, especially when someone isn’t menstruating or has systemic symptoms. Without that framework, real issues get mislabeled as “adrenal fatigue” or vague imbalance.

Natural approaches aren’t useless, but they operate in a different lane. Supplements and lifestyle can support hormones, but they don’t replace medical evaluation.
