Weight loss medication like Wegovy and Mounjaro have been a game changer, starting this weight loss journey often comes with a “learning curve” for your digestive system.
These medications work by slowing down gastric emptying and signaling your brain that you are full.
Because they change how your body processes food, your system needs time to recalibrate.
At McMinns Pharmacy, our Weight Loss Service in Wishaw focuses not just on the prescription, but on the clinical support required to manage these transitions comfortably.
The “Adjustment Phase”: Why Side Effects Happen
Most people experience side effects during two specific windows: when first starting the medication and each time the dose is increased.
These medications are usually started at a low “loading dose” to introduce the hormone to your body.
As you move up the dosage ladder (titration), your body may react to the higher concentration of the active ingredient.
The good news? For the vast majority of patients, these symptoms are temporary and subside as your body adapts.
Common Side Effects & How to Manage Them
Nausea and Vomiting
Nausea is the most frequently reported side effect. It usually peaks 24 – 48 hours after your injection.
-
-
- The Fix: Eat smaller, more frequent meals rather than three large ones. Avoid lying down immediately after eating. Bland foods like crackers, toast, or ginger tea can settle the stomach.
- Pro Tip: Try injecting your dose in the evening so you can sleep through the initial peak of the medication.
-
Changes in Bowel Habits (Constipation or Diarrhoea)
Because the medication slows down the movement of food through your gut, constipation is common.
Conversely, some people experience diarrhoea as their body adjusts to new hormonal signals.
-
-
- The Fix: It is vital to stay hydrated. Aim for 2–3 litres of water daily. If you are struggling with constipation, increasing your soluble fibre intake (oats, beans, lentils) or taking a gentle stool softener can help.
-
“The Burps” and Acid Reflux
You may notice “sulphur burps” or a feeling of indigestion. This happens because food stays in the stomach longer.
-
-
- The Fix: Avoid “trigger” foods that are high in fat, fried, or heavily spiced. These take even longer to digest and are more likely to cause reflux. Over-the-counter antacids can provide quick relief.
-
Fatigue
Feeling “wiped out” is common, especially in the first few weeks. This is often a combination of the medication itself and the fact that you are likely consuming significantly fewer calories than your body is used to.
-
-
- The Fix: Aim to include protein in every meal. Ensuring you hit your daily protein goals helps maintain energy levels and protects your muscle mass during weight loss.
-
When Side Effects Shift from “Normal” to “Noticeable”
While mild discomfort is expected, it is important to know when to seek help. Our pharmacists at McMinns Pharmacy monitor your progress closely to ensure your safety.
-
-
- Severe Abdominal Pain: If you experience intense pain that radiates to your back, seek medical attention immediately, as this could indicate a rare complication like pancreatitis.
- Persistent Vomiting: If you cannot keep fluids down, you risk dehydration.
-
Managing the Dose Increase
When it is time to move up to the next strength, treat that week as if it were your first.
Go back to basics: stick to bland foods, double your water intake, and get plenty of rest.
If side effects at a higher dose are unmanageable, our pharmacists may suggest staying at your current dose for an extra month to give your body more time to habituate.
