The Rise of Bariatric Surgery
Bariatric surgery is one of the fastest-growing weight loss interventions in the world, often portrayed as a quick fix for serious health concerns. But what’s the real story behind the hype?
It’s impossible to ignore the rising popularity of bariatric surgery. For some, it feels like a last resort. For others, it’s marketed as a miracle cure. Quick weight loss, fewer medications, lower risk of chronic illness – what’s not to love? But as with weight loss jabs, the story is more complex than it first appears.
Why? Because weight isn’t just about how much you eat—it’s also about how your body uses what you eat.
Bariatric surgery is not just about the stomach. It impacts digestion, nutrient absorption, hormones, and even the microbiome. And while it may help some people lose weight quickly, it can also come with hidden physical and emotional costs.
What Is Bariatric Surgery, Really?
It’s not just about shrinking the stomach — it’s about changing how your whole digestive system works. There are several types, but the most common include:
- Gastric bypass – reroutes part of the small intestine and reduces stomach size
- Sleeve gastrectomy – removes a large portion of the stomach
- Gastric banding – places a band to restrict stomach capacity
The goal in each case is to reduce food intake and, in some cases, nutrient absorption. Patients typically lose a significant amount of weight in the first 6 to 12 months.
Bariatric surgery reduces stomach size or reroutes digestion, making it physically difficult to eat large meals. People often lose weight rapidly in the first year or two. However, around 30% regain a significant amount of weight within five years.
The Promises and the Payoff
Let’s be fair: for some people, especially those with morbid obesity or serious health conditions, bariatric surgery can be life-changing.
- Rapid weight loss
- Improvement or reversal of type 2 diabetes
- Lowered blood pressure
- Relief from joint pain
- Improved mobility and mood
This 2022 systematic review highlights some of the long-term health benefits reported in select cases.
But these outcomes don’t happen in a vacuum. And they often come at a cost.
The Hidden Costs and Risks
Bariatric surgery isn’t just a physical change — it can trigger long-term nutritional, digestive, and emotional challenges:
-
Nutrient Deficiencies
Because the surgery alters the digestive tract, nutrient absorption can be seriously compromised. Deficiencies in B12, iron, calcium, magnesium and fat-soluble vitamins (A, D, E, K) are common and can lead to fatigue, hair loss, nerve problems, and osteoporosis.

Digestive Complications

More detail is outlined in this BMJ article on long-term complications. -
Mental Health Effects
Some patients report depression, regret, or disconnection from their body post-surgery. There can be grief around no longer being able to enjoy food or social meals. Others feel isolated by the changes in their eating and identity. Psychology Today article
This 2023 research shows an increased risk of suicide ideation among certain post-op groups. -
Weight Regain
Despite the dramatic early results, many people regain some or all of the weight within 2–5 years. Research published in Obesity Surgery
Dr. Mercola warns that unless root causes are addressed, the benefits of surgery are often temporary.
Why It Still Misses the Root Cause
You can change the size of the stomach, but if the underlying metabolic, hormonal, or emotional drivers aren’t addressed, weight loss will often be temporary. Like the weight loss jabs, surgery changes the mechanics of eating, not the underlying reasons why someone’s body was holding onto weight in the first place.
If someone has insulin resistance, sluggish thyroid function, mitochondrial dysfunction, unresolved trauma, chronic inflammation, or a toxic burden, cutting the stomach won’t solve those issues.
This functional health analysis explains why metabolic adaptation after surgery can still lead to weight plateaus or regain.
A More Compassionate Approach
Lasting results come when you work with your body, not against it — pairing any intervention with deep, root-cause healing. I’m not saying there is no place for bariatric surgery. For some, it may truly be a life-saving tool. But it’s not a standalone solution.
We need to pair any intervention with:
- Nutritional therapy to rebuild and repair
- Gentle detoxification support
- Hormone and gut rebalancing
- Emotional healing and nervous system regulation
- Sustainable lifestyle shifts
When we work with the body, not against it, we create the conditions for lasting change.
If you’ve been considering surgery, I encourage you to explore the deeper questions. Ask not just how to lose weight, but why your body gained it. That question holds the key to healing.
My Far Infrared Mineral Weight Loss Course provides a gentle, holistic framework for supporting weight loss through detoxification and energy balance. It includes online learning and the option of a 2-hour face-to-face module in the UK.
In the next post, we’ll look at one of the biggest hidden drivers of weight gain: mitochondrial decline. Could your tired cells be keeping you stuck? Stay tuned – and be kind to your body. It’s always trying to help you.
