GLP-1 Jabs, Weight Loss and Your Body — A Chinese Medicine Perspective

Everyone’s talking about them — Ozempic, Wegovy, Mounjaro — the weight-loss jabs that have taken over everything from celebrity gossip columns to GP waiting rooms. And if you're reading this, the chances are you're either curious about them, already taking one or thinking about what comes next when you stop.

This isn't a post telling you what to do. These are prescription medications for a reason and that decision belongs between you and your doctor. What I want to offer here is a different lens because when we look at what these drugs do through the eyes of Chinese medicine, some really interesting things emerge. And understanding that picture can make a significant difference to how you feel, both during treatment and afterwards.

What Are GLP-1 Jabs and How Do They Work?

GLP-1 stands for glucagon-like peptide-1, a naturally occurring gut hormone that your body produces when you eat. It tells the pancreas to release insulin, slows down how quickly the stomach empties food into the intestines and signals to the brain that you're full.

GLP-1 receptor agonists — the class of drug that includes semaglutide (Ozempic and Wegovy) and tirzepatide (Mounjaro) — mimic this hormone. They were originally developed for type 2 diabetes but are now widely used for weight management. They work by dramatically reducing appetite, slowing gastric emptying and quieting what many patients describe as constant "food noise."

The weight loss results are significant. Clinical trials report an average loss of 15–20% of body weight, but alongside these impressive results come some well-documented side effects: nausea, constipation, fatigue, muscle loss, hair loss and, crucially, the question of what happens when you eventually come off them.

Why Does Weight Gain Happen in the First Place? A TCM Perspective

Before we look at what these jabs do to the body, it's worth pausing on a question Chinese medicine asks first: why did the weight accumulate to begin with?

In TCM, unexplained or stubborn weight gain is rarely just about food. It is almost always a sign that something in the body's digestive system is not functioning as it should. The two organs most central to this are the Spleen and the Stomach.

The Spleen in Chinese medicine is the engine of digestion and transformation. It takes what we eat and drink and converts it into Qi and Blood — the vital substances that fuel every function in the body. When the Spleen is working well, we have good energy, clear thinking, healthy muscle tone and an appetite that feels balanced and intuitive.

The Stomach's job is to receive food, begin breaking it down and move everything onwards and downwards through the digestive system. The two organs work as a team. When both are functioning properly, the body processes food efficiently, extracts what it needs and eliminates what it doesn't.

But when the Spleen and Stomach are weakened by through chronic stress, irregular eating, overwork, emotional strain, years of dieting or simply the pace of modern life, their transformative function starts to break down. Food is not processed properly. Fluids accumulate and thicken into what TCM calls Dampness and Phlegm. This excess accumulates in the body as weight. This weight gain often occurs not because a person is eating too much or moving too little, but because the digestive system has lost its ability to transform and transport efficiently.

This is a fundamentally different way of understanding weight gain. It means that targeting food intake alone — however dramatically — does not fix the underlying problem. The Spleen and Stomach still need to be restored to full health for the body to regulate itself sustainably.

What GLP-1 Jabs Do — Through a TCM Lens

In Chinese medicine, we don't separate the body into isolated systems. Everything is interconnected — organs, emotions, digestion and energy all inform one another. So when we look at the effects of GLP-1 medications, we're not just looking at weight. We're looking at the whole picture of what shifts in the body.

Suppressing the Spleen and Stomach further

Here is where things get clinically important. GLP-1 jabs work by suppressing appetite and slowing gastric emptying — in other words, by forcing the Spleen and Stomach to do even less than they were already struggling to do. The weight comes off because food intake drops dramatically. But the digestive organs that were already weakened are now being suppressed rather than supported.

Over time this compounds the underlying Spleen Qi deficiency. The very system that needed rebuilding is instead being bypassed. This is why the side effects of these medications — fatigue, bloating, nausea, constipation, poor energy after eating, a feeling of heaviness or cold — read in TCM like a textbook description of Spleen and Stomach dysfunction because that is precisely what is happening.

Stomach Qi rebelling upwards

The Stomach's natural direction of movement is downwards — receiving food and moving it through the digestive tract. The nausea that affects around 70% of people on GLP-1 medications is, in TCM terms, a sign that this downward flow has been disrupted. We call it rebellious Stomach Qi — the Stomach’s energy is pushing upwards when it should be descending.

When appetite is suppressed for extended periods, Stomach Yin also becomes depleted. This shows up as persistent nausea, a dry mouth, reflux, constipation (the intestines need moisture to move), a reduced sense of taste or pleasure in food and, eventually, a deep disconnection from the body's natural hunger signals, which are the very signals that are supposed to guide healthy eating.

Blood deficiency, muscle wasting and hair loss

One of the more significant concerns with GLP-1 jabs is muscle loss. Research shows that a substantial proportion of weight lost on these medications comes not just from fat but from lean muscle mass. In Chinese medicine, the muscles are governed by the Spleen and muscle tissue is closely tied to Blood. When Blood is insufficient, the muscles become weak, the tendons lose their suppleness and the body feels depleted rather than vitally well.

Hair loss is another widely reported side effect — and in TCM this makes complete sense. The hair is said to be the "excess of Blood." When Blood becomes deficient, the body prioritises vital functions over what it considers non-essential. The hair thins. It is a visible sign of a deeper depletion.

For women especially, Blood deficiency has wide-reaching effects. Blood in TCM is the nourishing, cooling substance that supports the menstrual cycle, moistens the tissues, anchors sleep and stabilises emotions. Significant and rapid weight loss combined with reduced nutritional intake can leave women experiencing disrupted periods, worsening PMS, poor sleep, dry skin, anxiety or that unsettling feeling of being wired but utterly exhausted.

Bone density — an emerging and serious concern

This is one that is only now receiving the attention it deserves. A 2024 randomised controlled trial found that 52 weeks of once-weekly semaglutide reduced hip bone mineral density by 2.6% and lumbar spine density by 2.1% compared to placebo — with increased bone resorption and no compensatory increase in bone formation. A further study found that tirzepatide reduced total lean mass by nearly 11% over 72 weeks. These are not trivial findings, particularly for women.

It is worth noting that the picture is still emerging. Some studies in people using GLP-1 medications specifically for type 2 diabetes show a more neutral or even protective effect on bone. The concern appears to be most pronounced when these drugs are used primarily for weight loss — suggesting that it is the rapid loss of body mass and lean tissue, rather than the medication itself, that is doing much of the skeletal damage. Either way, the evidence is clear enough that bone health cannot be an afterthought for anyone on these medications.

In Chinese medicine, the bones are governed by the Kidneys. Kidney essence or Jing is what forms and nourishes bone tissue, maintains bone density and supports the structural integrity of the body. When Jing is depleted, the bones become less dense, more brittle and more prone to injury. This is exactly the process we see in osteoporosis and it maps precisely onto the bone density losses now being documented in GLP-1 research.

What Happens When You Come Off GLP-1 Jabs?

This is arguably the most important conversation happening right now and one that mainstream medicine is still catching up with. The majority of people who stop GLP-1 medications regain a significant proportion of the weight they've lost — often within a year. This is not a failure of willpower.

In Chinese medicine terms, it makes complete sense. The jabs suppressed the Spleen and Stomach rather than restoring them. The moment that suppression is lifted, the same weakened digestive system that struggled before is asked to function again — but now it is even more depleted than it was at the start. Appetite returns strongly. The body's hunger signals, confused after months of being overridden, swing back without the balance that a healthy Spleen would provide. And the Dampness and Phlegm that were never properly resolved begin to accumulate again.

The weight comes back not because the person has done something wrong, but because the root cause — a Spleen and Stomach that were not functioning properly — was never addressed.

This is the moment where acupuncture can make a profound difference.

How Acupuncture Can Help

Whether you are currently on a GLP-1 medication and want to feel better throughout, or you are coming off one and want genuine support during the transition, acupuncture offers something the jabs themselves cannot: treatment that addresses the root.

Restoring Spleen and Stomach function — properly

This is the foundation of everything. Rather than suppressing what the digestive organs do, acupuncture actively rebuilds their capacity to transform and transport. Points that tonify the Spleen and regulate the Stomach help restore the digestive centre from the ground up — improving appetite regulation, reducing bloating and nausea and supporting the body to process and absorb nutrients efficiently. When the Spleen and Stomach are functioning well, the body stops accumulating Dampness. Weight regulation begins to happen naturally, from the inside.

Nourishing Blood

By supporting the Spleen's ability to produce Blood and by using specific Blood-nourishing points, acupuncture addresses the depletion that comes with significant weight loss. This matters for muscle recovery, hair regrowth, menstrual health, sleep quality, skin condition and emotional steadiness — all the areas where Blood deficiency makes itself felt.

Supporting the Liver

When the body is under stress — and rapid change, even welcome change, is a form of stress — the Liver is often the first organ to feel it. Liver Qi stagnation can show up as frustration, irregular cycles, digestive discomfort and a tendency to feel wound up. Releasing Liver stagnation is a key part of helping the body settle and find its new equilibrium.

Restoring natural appetite signals

Rather than overriding the body's hunger and satiety mechanisms, acupuncture works to recalibrate them from within. Over time this helps re-establish the intuitive relationship with food and fullness that a healthy Spleen should provide — making sustainable weight management genuinely possible rather than dependent on ongoing medication.

Restoring Kidney Jing and supporting bone health.

Where there are signs of deeper depletion — reduced bone density, joint aching, pronounced hair loss, hormonal disruption, profound fatigue — constitutional points that support the Kidneys and Jing help to shore up the body's foundational reserves. Because the Kidneys govern bone in Chinese medicine, this is also where acupuncture can play a meaningful role in supporting skeletal health during and after a period of significant weight loss. This is particularly important for women in perimenopause, where bone density is already a concern, or those navigating a hormonal transition alongside the effects of coming off medication.

Addressing the emotional dimension

For many women, weight and appetite are deeply entangled with stress, self-worth and emotional eating. TCM has always understood the mind-body connection — each organ carries an emotional resonance — and acupuncture can help settle the nervous system, reduce anxiety and support a calmer, more grounded relationship with the body.

The Bigger Picture

GLP-1 medications have helped many people and I am not here to argue against that. But in Chinese medicine, we always ask: what is the root and what is the branch? The branch is the weight and accompanying symptoms. The root is often a Spleen and Stomach that have not been functioning as they should.

Suppressing those organs further — even temporarily, even with impressive results — does not fix the root. It delays the conversation the body has been trying to have. And when the medication stops, that conversation resumes.

Acupuncture offers a way to finally have it. To rebuild the digestive system properly, nourish what has been depleted and give the body the support it needs to regulate itself — not by force but by restoring function.
