In the last two years, weight-loss drugs have become the new obsession. From TikTok transformations to celebrities showing up 20 kilos lighter, the world suddenly believes there’s a magic injection that melts fat overnight. Even in Kenya, pharmacies are reporting an increased demand for drugs like Ozempic, Saxenda, Wegovy, Orlistat, and phentermine—sometimes from people who don’t even have prescriptions.
But behind the shiny results and viral “before and after” videos lies a story that most people don’t know: these drugs are powerful, effective for some, dangerous for others, and definitely not a quick fix.
So… How Do These Weight-Loss Drugs Actually Work?
Different drugs work differently, but most fall into three groups:
1. The GLP-1 Injections (Ozempic, Wegovy, Saxenda)
These are the ones dominating social media. They mimic a natural hormone that controls appetite and blood sugar.
They:
Make you feel full longer Reduce cravings Slow digestion Lower blood sugar
People can lose between 10–20% of their body weight within months. But they must be injected weekly.
2. Fat-Blockers (Orlistat / Alli)
These medications prevent about 30% of the fat in your food from being absorbed. But they also cause oily stools, diarrhea, and stomach cramps if you eat too much fatty food.
3. Appetite Suppressants (Phentermine and others)
These reduce hunger by acting on the brain. They work fast but can cause dependency, increased heart rate, and insomnia.
The Hidden Side of the Hype
What social media forgets to mention is that weight-loss drugs aren’t beauty products. They were created for people with:
Obesity Diabetes Serious weight-related health problems
For someone who only wants to drop “extra” 5kg for a vacation, the side effects may not be worth it.
Possible risks include:
Intense nausea and vomiting Severe diarrhea or constipation Low blood sugar Gallbladder issues Mood changes Hormonal disturbances Loss of muscle mass Weight rapidly returning when you stop the drug
Some women using contraceptives like Jadelle have also reported irregular bleeding when combined with certain appetite suppressants.
The Kenyan Reality: Cost, Access, and Misuse
A single injection of Saxenda or Wegovy can cost KSh 10,000–25,000 per week, depending on where you buy it. Ozempic is cheaper, but many sellers stock fake or diluted versions.
The biggest danger?
People using these drugs without a doctor’s assessment, often influenced by friends, influencers, or “online pharmacists.”
Without proper monitoring:
Diabetics can get dangerously low blood sugar Some people end up with severe dehydration Those with heart issues can get complications Medication can clash with contraceptives or chronic drugs
Do These Drugs Really Work? Yes — But With a Catch
They work best when combined with:
A calorie-controlled diet Exercise Stress management Adequate sleep Medical supervision
The moment someone stops injections and goes back to old habits, weight often rebounds. That’s why experts say these drugs are tools, not solutions.
So Who Should Actually Use Them?
Doctors usually recommend weight-loss medication only if:
Your BMI is above 30 OR your BMI is above 27 with health issues like diabetes, high blood pressure, PCOS, or sleep apnea You’ve tried lifestyle changes but are still struggling You’re under medical supervision
It is not recommended for:
Teenagers under 18 Pregnant or breastfeeding women People with a history of eating disorders Anyone with heart rhythm problems (for appetite suppressants) Anyone buying it without a prescription
The Truth We All Need to Hear
Weight-loss drugs can be life-changing. For someone battling obesity, they can prevent diabetes, heart disease, infertility, and even depression. They can save lives.
But for someone chasing “Instagram body goals,” the risks can outweigh the benefits—especially when done without guidance.
The truest weight-loss “secret” is this:
You don’t need to suffer to be beautiful, but you do need to be safe to stay alive.
If you ever consider weight-loss medication, talk to a doctor first. Your health is worth more than a trend.
