GLP-1 Medications (Ozempic, Mounjaro) and TCM — Supporting Your Body Through Treatment

By Dr (TCM) Attilio D'Alberto | Traditional Chinese Medicine Practitioner, Wokingham, Berkshire

The arrival of GLP-1 receptor agonist medications — semaglutide (Ozempic, Wegovy), tirzepatide (Mounjaro, Zepbound), and liraglutide (Saxenda) — has been one of the most consequential developments in diabetes and obesity medicine in decades. The weight loss they produce (15–20% of body weight on average) genuinely exceeds what was previously achievable with lifestyle change or earlier medications. Alongside the benefits, though, comes a well-documented side effect profile: approximately 70% of users experience some gastrointestinal symptoms, and there are legitimate concerns about muscle mass loss, fatigue, nutrient deficiencies, and how weight loss is maintained after stopping treatment. I am increasingly seeing patients in clinic who are on GLP-1s and want to know how traditional Chinese medicine can support them — not replace the medication, but make it work better and reduce the unwanted effects. That is what this article addresses.

What are GLP-1 medications?

GLP-1 receptor agonists mimic the action of glucagon-like peptide-1, a natural gut hormone that regulates blood sugar, appetite, and gastric emptying. They were originally developed for type 2 diabetes and work through several mechanisms: they promote insulin release when blood sugar rises, suppress glucagon (which raises blood sugar), slow the rate at which the stomach empties, and act on appetite centres in the brain to reduce hunger and food-related thoughts — the "food noise" that many patients describe quieting on treatment. The weight loss results from eating meaningfully less, and from the metabolic effects of the drug itself.

The major agents currently in UK use are semaglutide (branded Ozempic for diabetes, Wegovy for weight loss), tirzepatide (Mounjaro — a dual GLP-1 and GIP agonist producing larger weight losses), and liraglutide (Saxenda). Orforglipron, an oral GLP-1 agent, is approaching approval. NHS access remains limited but private prescribing has grown rapidly, with pharmacies and online clinics offering these medications widely.

To be clear from the outset: GLP-1 medications work. They treat real conditions effectively. Nothing in this article should be read as opposing their use. What I see clinically is that they work considerably better when the body is supported through the transition — nausea is reduced, energy is maintained, muscle is preserved, and long-term outcomes improve.

Common side effects and their patterns

The side effect profile of GLP-1 medications is well-characterised. In non-diabetic adults with overweight or obesity, approximately:

• Nausea — the most common side effect, occurring in roughly 40–50% of users, particularly during dose escalation
• Vomiting — 15–20%, more common at higher doses and with faster escalation
• Diarrhoea — 20–30%
• Constipation — 15–25%, particularly with semaglutide and liraglutide
• Bloating and early satiety — near universal to some degree
• Fatigue — common, especially during the first months
• Dizziness and headaches
• Muscle loss — approximately 20–30% of total weight lost comes from lean mass (similar to other weight-loss methods, but a concern given rapid loss)
• Reduced bone density — with sustained weight loss
• Mood changes — some patients report emotional flattening or low mood
• Hair thinning — often reflects the rapid weight loss and associated nutritional demand
• Gallbladder issues — rapid weight loss increases gallstone risk

Most gastrointestinal side effects settle as the body adjusts, typically within 4–12 weeks of a stable dose. Some patients, however, have persistent symptoms, and a meaningful minority discontinue the medication as a result.

The TCM view of GLP-1 side effects

The side effect profile of GLP-1 medications maps remarkably well onto a predictable set of TCM patterns. The drug's primary action — slowing gastric emptying and reducing appetite — affects exactly the organ systems TCM calls the Spleen and Stomach. The digestive and energy symptoms arise because the body's capacity to transform food into qi is temporarily reduced.

Stomach qi rebellion explains the nausea and vomiting. Normally Stomach qi descends, carrying food and waste downward. When the stomach is distended or sluggish, Stomach qi rebels upward, producing nausea. This is the same pattern that underlies pregnancy nausea, travel sickness, and chemotherapy-induced nausea — all of which respond well to the same points and herbs.

Spleen qi deficiency develops when the reduced food intake and slowed digestion leave the Spleen underfunctioning. This produces fatigue, bloating, loose stools (or the opposite — constipation from qi too weak to move the bowels), and poor muscle tone. The muscle loss that concerns endocrinologists is, in TCM terms, a classical sign of Spleen qi deficiency: the Spleen "governs the flesh and limbs."

Liver qi stagnation often accompanies the above. The emotional effort of weight loss combined with slower digestion produces classic Liver qi stagnation symptoms — irritability, bloating, premenstrual intensification in women, and the mood flatness some patients describe.

Kidney yang depletion can develop in sustained use, particularly in older patients or those with rapid weight loss. The cold, fatigue, low libido, and general depletion some patients experience reflect the body's reserves being drawn on to compensate for reduced nutritional intake.

The pattern I see most commonly is Spleen qi deficiency with Stomach qi rebellion, often with secondary Liver qi stagnation — which gives the combined picture of nausea, fatigue, bloating, and mood effects.

Managing nausea, vomiting and gastrointestinal symptoms

The PC 6 (Neiguan) acupuncture point is one of the most evidence-based interventions for nausea of any cause. A Cochrane review confirmed its effectiveness for pregnancy nausea, and multiple RCTs support its use in post-operative and chemotherapy-induced nausea. For GLP-1-related nausea, it is equally effective. Key interventions:

• Sea-Band wristbands worn over PC 6 — cheap, over-the-counter, and genuinely helpful. Worth trying before any other intervention.
• Self-applied PC 6 acupressure — firm pressure for 1–2 minutes when nausea hits. Three fingers' width above the wrist crease on the inner forearm.
• Acupuncture at PC 6, ST 36, and CV 12 — the classical combination for nausea and gastric disorders. Weekly sessions during the dose escalation phase significantly reduce symptoms for most patients.
• Ginger — 1g daily of fresh ginger or ginger capsules has clinical evidence for nausea. Ginger tea with meals can help.
• Small, frequent meals — slow gastric emptying means large meals produce prolonged fullness and nausea. Graze rather than binge.
• Avoid fatty and fried foods — fat slows gastric emptying further, worsening nausea
• Avoid drinking during meals — drink between meals; drinking during eating distends the already-slow stomach
• Chinese herbal formulas — modifications of Ban Xia Hou Po Tang or Xiao Ban Xia Tang specifically address Stomach qi rebellion and can be tailored to individual presentations

Constipation and slow gastric emptying

The same mechanism that produces satiety — delayed gastric emptying — can produce significant constipation. Slow transit through the stomach, combined with reduced food volume and often reduced fluid intake, is a reliable recipe for constipation. TCM approaches:

• Adequate fluid intake — reduced appetite often means reduced drinking. Aim for 1.5–2 litres daily of water, warm water, or herbal tea.
• Adequate fibre — especially soluble fibre from vegetables, oats, flaxseed, chia seed. Avoid relying on protein shakes alone, which can worsen constipation.
• Magnesium — magnesium citrate (300–600mg at night) is gentle, effective, and addresses the widespread magnesium deficiency that develops on GLP-1s.
• Abdominal massage — clockwise around the navel for 5 minutes daily supports bowel transit.
• Acupuncture points — ST 25 (Tianshu), ST 36, and SP 15 for bowel regulation.
• Herbs — formulas like Ma Zi Ren Wan for constipation with qi deficiency, or gentler bowel-regulating formulas, address the underlying pattern rather than just producing a laxative effect.
• Movement — walking after meals helps gastric emptying and bowel function significantly

Fatigue, low energy and muscle loss

Many patients are surprised by the fatigue that develops on GLP-1 medications. The combination of reduced calorie intake, rapid weight loss, muscle mass reduction, and underlying nutritional gaps produces a fatigue that lifestyle alone cannot fully address. Preventing muscle loss is particularly important because muscle is the primary site of glucose uptake, the driver of metabolism, and the protector against frailty in later life.

• Prioritise protein — at least 1.6g per kg of body weight daily, ideally more. This is the single most important intervention for preserving muscle. Spread across meals — 25–35g at each meal for optimal muscle protein synthesis.
• Resistance training is non-negotiable — at least two sessions weekly of compound lifts (squat, deadlift, press, row). The muscle you stimulate through resistance training is the muscle the body will prioritise retaining during weight loss.
• Creatine monohydrate — 3–5g daily. Cheap, safe, well-studied, and supports both muscle mass preservation and cognitive function on reduced-calorie intake.
• Chinese herbal tonics — formulas with Huang Qi (astragalus), Ren Shen (ginseng), and Bai Zhu (atractylodes) directly address the Spleen qi deficiency that produces fatigue. See my articles on astragalus benefits and atractylodes benefits.
• Acupuncture — weekly acupuncture through the initial months significantly reduces fatigue and supports overall recovery. Key points include ST 36, CV 4, CV 6, and BL 23.
• Adequate sleep — 7–9 hours, which is when muscle repair and growth hormone release occur. See my article on sleep optimisation from a TCM perspective.
• Don't under-eat — some patients take the reduced appetite as permission to eat very little. This accelerates muscle loss and worsens fatigue. Eat enough protein and nutrient-dense food even when appetite is low.

Nutrient deficiencies

Reduced food intake over sustained periods produces predictable nutritional gaps. Key deficiencies to watch:

• Magnesium — often the first to deplete; produces fatigue, muscle cramps, poor sleep, constipation, and anxiety. Magnesium glycinate (200–400mg) is well-absorbed and gentle on digestion.
• B vitamins — particularly B1, B6, B12. A B-complex daily supports energy production.
• Iron — particularly in menstruating women. Check ferritin as well as haemoglobin.
• Vitamin D — assess annually; supplement at 2,000 IU daily minimum in the UK October–March.
• Protein — discussed above; the single most important macronutrient on GLP-1s.
• Omega-3 fatty acids — reduced fish intake often accompanies reduced appetite; 2g daily of EPA/DHA supports mood, inflammation, and cardiovascular health.
• Calcium — important for bone density protection alongside weight loss.

A comprehensive blood panel before starting GLP-1 and then at 6 and 12 months identifies deficiencies before they become problematic. Most patients benefit from a high-quality multivitamin, magnesium, vitamin D, omega-3, and adequate protein as baseline supplementation.

Emotional and psychological effects

An under-discussed aspect of GLP-1 treatment is the emotional shift many patients experience. The reduction in "food noise" is usually welcome, but some patients describe a broader emotional flattening — less pleasure from food, less drive, reduced spontaneous joy. Others describe low mood or anxiety. In TCM terms, this often reflects the medication's effect on the Liver and Heart systems — food is a deep source of Spleen qi and Heart joy, and when that is quieted, the emotional register shifts.

Acupuncture is particularly helpful for this dimension — regulating the Liver qi flow and supporting Heart shen. Patients frequently report that acupuncture restores some of the emotional texture that feels muted on the medication, without reducing the medication's benefits. For persistent low mood, it should be discussed with the prescribing clinician — sometimes a dose reduction or medication change is appropriate.

Coming off GLP-1 and maintaining results

A significant clinical question is what happens when treatment stops. Studies show that most weight is regained within 12 months of discontinuation if no active maintenance strategy is in place. This has led to the increasing view that GLP-1 is a long-term treatment for obesity, much as antihypertensives are long-term treatment for blood pressure. However, some patients want to come off — due to cost, side effects, or simply wanting to try — and TCM can meaningfully support this transition.

The key principles for maintaining weight loss after GLP-1 discontinuation include preserved muscle mass (the most important factor), established exercise habits (particularly resistance training), stable blood sugar regulation, protected sleep, stress management, and active digestive health. TCM contributes by regulating appetite through Spleen and Stomach support, managing the emotional eating patterns that often drive weight regain (Liver qi stagnation), and supporting the metabolic flexibility that independent maintenance requires. A course of acupuncture and herbs during the transition off medication — typically 3–6 months — significantly improves outcomes.

Frequently asked questions

Should I stop my GLP-1 medication to try TCM instead?

No. GLP-1 medications treat real conditions effectively, and TCM is best positioned as a complement that makes the medication work better with fewer side effects — not as a replacement. If you want to reduce or stop the medication, discuss it with your prescribing doctor, and consider TCM support for the transition.

Will acupuncture interfere with my GLP-1?

No — there is no pharmacological interaction. Acupuncture works through different mechanisms (neural, hormonal, anti-inflammatory) and is entirely compatible with GLP-1 treatment. Patients often find it reduces side effects and makes the overall experience more tolerable.

Can Chinese herbs interact with GLP-1 medications?

Most TCM formulas are compatible, but some herbs that affect glucose metabolism (bitter melon, cinnamon in high doses, some diabetes-targeted formulas) could theoretically produce additive blood sugar lowering. I always ask about current medications before prescribing and tailor formulas accordingly. Herbs should only be prescribed by a practitioner registered with the Register of Chinese Herbal Medicine.

How do I stop losing muscle on Ozempic or Mounjaro?

Three key interventions: high protein intake (1.6g per kg body weight daily minimum), resistance training at least twice weekly, and creatine supplementation (3–5g daily). Chinese herbal tonics supporting Spleen qi (astragalus, ginseng, atractylodes) help preserve the physiological basis of muscle. Avoid eating too little — severe calorie restriction accelerates muscle loss.

Why am I so tired on GLP-1 medication?

Common reasons include reduced calorie intake, nutritional deficiencies (particularly magnesium, iron, B12, protein), muscle loss, and the Spleen qi deficiency pattern this produces in TCM terms. A blood panel plus targeted supplementation, strength training, and acupuncture typically addresses this within 4–8 weeks.

Can I prevent the side effects of GLP-1 medications before they start?

Often yes. Starting with a slower dose escalation, beginning acupuncture at the start of treatment, ensuring adequate hydration and nutrition, and starting Sea-Band wristbands preventatively all reduce the severity of side effects. Patients who prepare proactively generally have a smoother experience.

What happens when I stop taking GLP-1?

Without active maintenance, most people regain the majority of lost weight within 12 months. Appetite returns, often more strongly than before treatment. To maintain results, muscle mass must be preserved, exercise habits established, and the underlying patterns (stress eating, sleep deprivation, emotional dysregulation) addressed — exactly what TCM and lifestyle change can support.
