People are tired of diets that don’t last, and they’ve heard that “ **the weight loss injection**” can finally move the needle. The reality is more nuanced: - These injections are **powerful prescription medicines**, not beauty treatments - They **don’t work for everyone**, and they’re **not risk-free** - They’re only safe when used **under medical supervision**, never as “weight loss injections without prescription” In this guide, you’ll learn how weight loss injections work, who they’re for, the risks to know about – and why a structured, doctor-led programme like **Piko** is one of the safest and most effective ways to use them. * * * ## First, what is Piko – and why are we different? **Piko** is a **digital medical weight-management clinic** for people in the UK who are considering evidence-based treatment, including GLP-1–based weight loss injections where appropriate. We focus on three things: ### 1\. Life-changing, evidence-based results Clinical trials of modern **GLP-1–based weight management medicines** show average weight loss of about **10–15% of body weight over ~1 year** when combined with lifestyle support. In real programmes, many patients reach around **10% body-weight reduction over the first 3–6+ months**, depending on dose, adherence and starting point. Results vary, but this level of loss can: - Improve blood pressure, blood sugar and cholesterol - Reduce sleep apnoea risk - Boost confidence, mobility and day-to-day energy Piko’s protocols are built around this clinical evidence – always combined with nutrition, movement and habit coaching so weight loss is **healthier and more sustainable**, not just a quick drop on the scale. > **Important:** No provider can _guarantee_ a specific result. Your outcome depends on your body, your health and how you use the programme. We’ll be honest about what’s realistic for you. ### 2\. Affordable, flexible access Traditional weight loss clinics often charge **£300–£500+ per month** for programmes that combine consultations, labs and medication. At Piko, we’ve designed our pathway so that **full medical support + app + ongoing follow-up** can start from **under ~£3 per day** (roughly equivalent to 3€), in **monthly plans you can cancel** if circumstances change. You get: - A clear, all-inclusive price (no surprise “admin fees”) - A digital journey that cuts overheads – and passes savings to you - Options to adjust your plan as your needs change ### 3\. Guided by expert doctors, 24/7 support Weight loss injections are **not** DIY treatments. With Piko you get: - **Initial medical assessment** with a UK-registered doctor - **Eligibility check** against current NICE/NHS guidance and product licences - **Monthly medical follow-ups** while you’re on treatment - **24/7 in-app chat** so you can ask questions, report side effects and get timely adjustments - Integrated **coaching, tracking and education** in the same app If medication isn’t appropriate or safe for you, we’ll say so – and help you explore **non-medication options** instead. * * * ## What people actually mean by “the weight loss jab” When people talk about **“the weight loss jab”**, they’re usually referring to **injectable medicines for obesity** that were originally developed for **type 2 diabetes** and later licensed for weight management. Most of the current “weight loss shots” used in the UK fall into these categories: - **GLP-1 receptor agonists** – medicines that mimic a gut hormone called GLP-1 - **Dual or multi-hormone agents** that act on **GLP-1 plus other pathways** (for example GIP) You might see them described as: - **Weekly weight loss injections** - **Daily weight loss injections** (older formulations) - **Weight loss shots in the stomach** (because they’re injected into the abdomen or thigh) They are **prescription-only medicines** (POMs). That means: - You **must** have a prescription from a qualified prescriber - They should only be dispensed by a **registered pharmacy** - They’re **not allowed** to be promoted directly to the public as products by name under UK advertising rules * * * ## How weight loss injections work in the body (in plain English) Most modern weight-management injections work by acting on **hormones that control appetite and blood sugar**. They: - **Slow stomach emptying** → you feel fuller for longer after eating - **Act on appetite centres in the brain** → many people feel less driven to snack or overeat - Can improve **insulin sensitivity and blood sugar control**, especially if you have pre-diabetes or type 2 diabetes The result for many patients is: - Smaller portions feel satisfying - Fewer cravings and less “food noise” - A realistic path to **10%+ weight loss** when combined with diet and movement changes But they **don’t**: - Magically burn fat while you keep the exact same habits - Work equally well for everyone - Replace the need for **healthy eating, movement and sleep** That’s why Piko combines any medication with a **structured lifestyle programme** instead of just shipping pens to your door. * * * ## Who are weight loss injections for? Eligibility is based on **BMI plus health conditions**, as well as a proper medical assessment. Exact criteria depend on the specific medicine and on whether you’re going through the **NHS** or a **private clinic**, but broadly: ### NHS criteria (high-level overview) NHS access is targeted at people with the **highest medical need** and usually includes: - **Obesity with weight-related conditions**, typically after trying other options - BMI cut-offs (for example, NICE guidance for some GLP-1 treatments has used thresholds like BMI ≥35 with at least one comorbidity, or BMI 30–34.9 with comorbidities in specialist services). - For some newer injections (such as dual-hormone agents), NHS England has stated that early rollout is for people with **BMI ≥40 plus several serious weight-related conditions**, with adjusted thresholds for certain ethnic groups. Criteria are tightening and evolving as demand and supply change, so you always need **up-to-date advice from your own doctor**. ### Private clinics (including digital services like Piko) Private providers must still follow: - **Product licences** - **NICE guidance** - **Professional standards** for safe prescribing Many will consider adults with: - **BMI in the obesity range** (for example ≥30), or - **BMI in the high-overweight range** (for example ≥27) **plus weight-related health problems**, such as high blood pressure, high cholesterol, sleep apnoea or pre-diabetes At Piko, our clinicians: - Use **current national guidance** as a starting point - Do a full **risk–benefit assessment** with you - Consider other medicines you’re on and your medical history - May recommend **no injection**, or a different approach, if they believe it’s safer * * * ## Common side effects and safety considerations Like all powerful medicines, **weight loss jabs come with side effects and risks**. The most common side effects in clinical trials of GLP-1–based medicines include: - **Nausea** - **Vomiting** - **Diarrhoea or constipation** - Abdominal discomfort or bloating - Loss of appetite These are usually **mild to moderate** and often improve as your body adapts, especially if the dose is **increased slowly**. More serious, less common risks can include: - **Gallbladder problems** (e.g. gallstones) - **Pancreatitis** (inflammation of the pancreas) - Possible effects on certain eye conditions in people with diabetes - Very rare severe allergic reactions You **shouldn’t** use many of these medicines if you: - Have certain types of **severe gastrointestinal disease** - Have a history of certain rare endocrine tumours - Are pregnant, planning pregnancy soon, or breastfeeding This is exactly why **self-injecting a “skinny jab” bought online is dangerous** – you have no proper medical screening, no checking of interactions, and no follow-up. In Piko programmes: - Every patient has their **medication choice, dose and escalation** tailored by a doctor - You have **monthly medical reviews** plus **in-app chat** to flag side effects early - We adjust dosage or pause treatment if needed – safety before speed * * * ## NHS vs private access: what’s the difference? ### On the NHS - Access is **free at the point of care**, but limited to **strictly defined high-risk groups** - Medicines are usually prescribed through **specialist weight management services** or specific GP programmes - Capacity is limited and **waiting lists** can be long ### Privately (including Piko) - You pay out of pocket, but: - There is **more flexibility** in how quickly you can be seen - You can sometimes start treatment sooner if you’re eligible - You should still only use **regulated providers** with: - UK-registered prescribers - UK or EU registered partner pharmacies - Clear medical criteria and follow-up With Piko specifically, the private pathway looks like this: 1. **Online eligibility quiz** → helps you understand whether medical treatment _might_ be suitable 2. **Doctor video consultation** → full medical history, medications and goals 3. **Shared decision** on whether to use a weight loss injection, another option, or lifestyle-only support 4. **Medication prescribed (if appropriate)** through partner pharmacies 5. **Ongoing monthly reviews + app tracking + coaching** This gives you NHS-style clinical governance with **digital convenience and flexibility**. * * * ## A serious warning on “weight loss injections without prescription” and “skinny jabs” Because demand is huge, the UK has seen a wave of: - **Counterfeit pens** containing unknown substances - Unlicensed products being made in illegal factories - “Clinics” and influencers advertising **“the skinny jab”** with no proper medical oversight The **MHRA** has issued multiple warnings about **fake weight-loss pens**, including falsified GLP-1 products discovered in UK supply chains and on social media. The **ASA (Advertising Standards Authority)** has: - Banned **“skinny jab” influencer posts** for illegally promoting prescription-only medicines - Issued enforcement notices to online pharmacies that were advertising “weight loss injections” directly to the public, in breach of rules on POM promotion. > **If someone offers you a “weight loss jab” or “slimming injection” without a prescription, run – don’t walk – in the other direction.** Red flags include: - “Deals” via **Instagram DMs, WhatsApp, TikTok, Snapchat** - Sellers who can’t show they’re a **UK-registered prescriber or pharmacy** - Products in **unbranded pens, vials or powders** - Claims like “no side effects” or “no medical history needed” - “Bootleg” or “research” versions of branded medicines These products can: - Contain **wrong doses or completely different drugs** - Be contaminated or made with **zero quality control** - Lead to severe side effects, hospitalisation, or worse Piko only prescribes **licensed medicines** from **regulated pharmacies**, and only **after a proper medical consultation**. * * * ## Why choose Piko for medical weight loss in the UK?
