Managing Side Effects on Mounjaro, Wegovy or Foundayo

Mounjaro, Wegovy and Foundayo affect appetite pathways and can slow the rate at which food leaves the stomach. This can increase fullness and reduce hunger, but it can also contribute to nausea, reflux, bloating and changes in bowel habits.

Symptoms are often more noticeable when treatment begins or after a clinically approved dose increase. Large meals, rich foods, dehydration, eating quickly or increasing fibre too suddenly can make some symptoms worse.

Many digestive side effects improve over several days or weeks as the body adjusts. They may return temporarily after a clinically approved dose increase.

There is no fixed settling period for everyone. Contact LIVVE if symptoms are worsening rather than improving, continue to interfere with daily life, or prevent adequate eating and drinking.

• Eat smaller meals rather than waiting until very hungry.
• Eat slowly and stop when comfortably satisfied.
• Avoid very large, greasy, fried or rich meals.
• Stay upright after eating rather than lying down immediately.
• Drink regularly, taking smaller sips if large drinks feel uncomfortable.
• Notice whether certain foods, alcohol or late meals trigger symptoms.

A pharmacist may recommend a suitable short-term treatment for reflux, nausea, constipation or diarrhoea after checking symptoms, medicines and health conditions. Regular antacids, laxatives or anti-diarrhoeal medicines should not be started without advice when symptoms are severe, recurrent or unexplained.

• Drink regularly throughout the day.
• Include fruit, vegetables, oats, wholegrains or pulses as tolerated.
• Increase fibre gradually rather than suddenly.
• Keep gently active where possible.
• Respond to the urge to open your bowels rather than delaying.
• Ask a pharmacist or LIVVE about suitable treatment if lifestyle measures are not enough.

Vomiting and diarrhoea can lead to dehydration. This is particularly important for people with kidney problems, diabetes or medicines affected by fluid balance.

• Dark urine or passing urine less often.
• Dizziness, weakness or headache.
• Dry mouth or intense thirst.
• Feeling faint when standing.
• Difficulty keeping fluids down.

Use small, regular sips if drinking a full glass feels difficult. Contact LIVVE for repeated vomiting or diarrhoea, and seek urgent advice if fluids cannot be kept down or significant dehydration develops.

Hair shedding can sometimes occur during significant or rapid weight loss. It may relate to the physical stress of weight change, low protein or nutrient intake, menopause, thyroid health, iron deficiency or another cause rather than a direct medicine effect alone.

Contact LIVVE if hair loss is marked, persistent or accompanied by fatigue, scalp symptoms or other health changes. Review may include weight-loss rate, nutrition, menstrual history, menopause symptoms and whether blood tests are appropriate.

Mild redness, itching, bruising or tenderness can occur where Mounjaro or Wegovy injections are given. Rotate injection sites and follow the pen instructions supplied with the medicine.

Mounjaro, Wegovy or Foundayo used alongside insulin or certain diabetes medicines can increase the risk of low blood sugar. Symptoms may include sweating, shaking, hunger, dizziness, confusion, weakness or a racing heartbeat.

Follow the treatment plan given by the diabetes team and keep any recommended hypo treatment available. Contact a clinician promptly if low blood sugar occurs or glucose readings change significantly. Do not alter insulin or other diabetes medicines without advice.

A dose increase should never be automatic. A clinician may recommend remaining at the current dose for longer, delaying an increase or reviewing whether treatment remains suitable if side effects have not settled.

• Whether symptoms are improving, stable or worsening.
• Whether food and fluid intake remain adequate.
• Constipation or dehydration risk.
• Appetite response and weight trend.
• Other health conditions and medicines.
• Whether treatment can be used correctly and consistently.

Nausea, bloating, fatigue, mood changes, sleep disruption and appetite changes can overlap with menopause symptoms, HRT effects, low food intake, dehydration, stress or another health problem.

A review may need to consider timing, HRT use, bleeding, nutrition, sleep, bowel symptoms and whether the change followed starting or increasing weight-loss treatment.

If you use Foundayo and take an oral hormonal contraceptive, tell LIVVE. Orforglipron may reduce the effectiveness of oral hormonal contraception, so a non-oral method or an additional barrier method is advised for 30 days after starting Foundayo and for 30 days after each dose increase.

Gallstones and gallbladder inflammation can occur during weight loss, particularly when weight falls quickly. Seek urgent clinical advice for persistent pain under the right ribs or in the upper abdomen, especially with fever, vomiting, yellowing of the skin or eyes, dark urine or pain spreading towards the shoulder or back.

Patients and healthcare professionals can report suspected medicine reactions through the MHRA Yellow Card scheme. Reporting does not replace contacting LIVVE or seeking urgent medical help.

• How to tell whether treatment remains manageable: food and fluid intake, daily functioning and whether symptoms are improving.
• Preparing for review: what symptoms to record, what has helped and whether the current plan remains suitable.

Do not wait for the next email. Contact LIVVE sooner if symptoms are persistent, worsening, affecting eating or drinking, or making you unsure about the next dose.

• Which symptoms you have and when they started.
• Whether they followed starting treatment or a dose increase.
• How often they occur and whether they are improving.

• Any vomiting, diarrhoea, constipation or reflux.
• What practical measures you have tried and whether they helped.
• Any missed doses or uncertainty about the next dose.

Is nausea normal on Mounjaro, Wegovy or Foundayo?

Nausea is common, especially when treatment starts or after a dose increase. It should remain manageable and often improves as the body adjusts. Contact LIVVE if it is persistent, worsening, stops you eating or drinking, or occurs with repeated vomiting or severe pain.

What helps constipation?

Drink regularly, keep moving as tolerated and increase fibre gradually rather than suddenly. Contact LIVVE or a pharmacist if constipation persists, becomes painful or occurs with vomiting, marked bloating or inability to pass wind.

Can Mounjaro, Wegovy or Foundayo cause reflux?

Yes. Slower stomach emptying, larger meals, rich foods and lying down soon after eating can contribute. Smaller meals, slow eating and avoiding late or greasy meals may help.

What if I cannot eat enough?

Contact LIVVE. Very strong fullness, nausea or fear of eating can cause low fluid and nutrient intake. Small nutrient-dense meals may help temporarily, but suitability needs review.

When should I seek urgent help?

Seek urgent medical advice for severe persistent abdominal pain, repeated vomiting with dehydration, severe allergic symptoms, sudden vision changes, or severe constipation with pain, vomiting, marked bloating or inability to pass wind or stool.

How long do Mounjaro, Wegovy or Foundayo side effects last?

Many common digestive symptoms improve over several days or weeks, although they may return after a dose increase. Contact LIVVE if symptoms worsen or prevent adequate food and fluid intake.

Can Mounjaro, Wegovy or Foundayo cause hair loss?

Hair shedding may occur during significant or rapid weight loss and can also relate to nutrition, menopause, iron deficiency, thyroid health or another cause. Contact LIVVE if it is marked or persistent.

Can Mounjaro, Wegovy or Foundayo cause low blood sugar?

The risk is greatest with insulin or certain diabetes medicines. Seek advice for sweating, shaking, confusion, dizziness, weakness or a racing heartbeat, and do not change diabetes medicines without guidance.

Are Foundayo side effects the same as Wegovy tablet side effects?

They can overlap, but the medicines are different. Wegovy tablets contain semaglutide and Foundayo contains orforglipron. Both can cause digestive side effects such as nausea, constipation, diarrhoea, vomiting, indigestion and abdominal discomfort. Their practical instructions also differ: Wegovy tablets require a specific fasting routine, while Foundayo can be taken without food or water restrictions. Foundayo also has specific advice for people using oral hormonal contraception, so tell LIVVE about all medicines and contraception you use.
