Is weight loss with medication safe in the long term?

Losing weight with medication is safe in the long term when it takes place under the guidance of a doctor, with the correct indication and regular medical monitoring. Safety depends strongly on the type of medication, the individual health situation and the way in which use is monitored. The questions below answer the most frequently asked questions about the safety, efficacy and responsible use of weight-loss medication.

What are the risks associated with the long-term use of weight-loss medication?

Long-term use of weight-loss medication carries risks that vary per person and per type of medication. The most common side effects of GLP-1 medication are gastrointestinal complaints such as nausea, diarrhoea and a reduced appetite. With long-term use, changes in digestion, muscle mass or nutrient absorption may also occur. Risks are manageable with medical supervision, but never completely absent.

Side effects of weight-loss medication disappear for many people after the first few weeks of use, once the body gets used to how the medicine works. Even so, it remains important to stay alert, even in the longer term, to signs that could point towards unwanted effects. Think of persistent abdominal pain, changes in heart rhythm, or unexplained weight loss that happens faster than expected.

Another point of attention with long-term use is the risk of malnutrition or vitamin and mineral deficiencies, as appetite can decrease significantly. People who for a long time weight loss medication use, benefit from periodic checks of blood values and nutritional status.

How does waste medication work in the body over time?

GLP-1 medication works by mimicking a hormone that naturally occurs in the body and plays a role in regulating blood sugar and satiety. Over time, this leads to a reduced feeling of hunger, slower gastric emptying and a lower calorie intake. The body gradually adapts, which means that the effect on weight loss may plateau over the course of months.

In the first few weeks of use, weight loss is most pronounced for many people. As treatment continues, this effect often plateaus. This is not a sign that the medication is no longer working, but a normal physiological process whereby the body seeks a new equilibrium.

Crucially, weight-loss medication does not directly stimulate fat burning, but rather influences the energy balance via appetite regulation. This means that lifestyle factors such as diet and exercise continue to play an enduring role alongside the use of medication. Weight-loss medication works best as part of a broader programme, not as a replacement for healthy habits.

What happens when you stop taking weight-loss medication?

When people stop taking weight-loss medication, for most the feeling of hunger returns to the pre-treatment level. This can lead to weight gain, especially if no sustainable lifestyle changes have been made during use. Stopping medication without guidance increases the risk of the so-called yo-yo effect.

The extent of weight gain after stopping varies greatly per person and depends on factors such as the duration of use, the degree of behavioural change during treatment and individual metabolism. People who have also adjusted their diet and exercise habits during their treatment path generally maintain more of the weight loss achieved.

Stopping waste medication should always be done in consultation with a doctor. A doctor can assess whether tapering off should be gradual and what additional support is useful to maintain the achieved result.

For whom is weight-loss medication suitable in the long term?

Long-term weight-loss medication is generally suitable for people with medically diagnosed overweight or obesity where other methods have produced insufficient results. A doctor assesses per person whether long-term use is medically justifiable, based on health history, weight, blood values and other factors. Not everyone is eligible.

People with certain conditions, such as a history of thyroid cancer, pancreatitis or severe gastrointestinal problems, may not be eligible for specific types of weight-loss medication. Pregnancy and breastfeeding are also situations where use is generally not recommended. These are medical assessments that only a doctor can make.

Long-term use is most beneficial for people who are also willing to work on lifestyle changes. Medication supports the process, but does not replace the need for a healthy diet and exercise routine. A realistic set of expectations and active involvement in one's own journey increase the likelihood of lasting results.

How does safe use differ from uncontrolled use?

Safe use of leftover medication is distinguished from uncontrolled use by three factors: a medical indication, a doctor's supervision, and medication obtained via a registered pharmacy. Uncontrolled use, for example via foreign websites or without a prescription, entails significant risks, including fake or incorrectly dosed substances and a lack of medical follow-up.

Risks of uncontrolled use

People who purchase weight-loss medication without medical supervision run the risk of incorrect dosage, interactions with other medicines, and the use of products that have not been approved by the Dutch or European medicines authorities. In such cases, side effects are not recognised or treated in time.

Characteristics of responsible use

When used responsibly, the medication is prescribed by a BIG-registered doctor following a careful medical assessment. The pharmacy checks the prescription independently before the medication is dispensed. Throughout the process, there is the opportunity to contact a doctor in the event of questions or complaints. Prescription-only medication is never supplied without these steps.

When should you consult a doctor during a treatment process?

During a course of treatment with weight-loss medication, it is advisable to consult a doctor in the event of persistent or severe side effects, if there is any doubt about the progress of the treatment, or if changes occur in your health situation. Do not wait for a scheduled check-up if you experience symptoms that feel acute or are worsening.

Concrete situations where contact with a doctor is necessary include:

• Severe or persistent nausea, vomiting, or abdominal pain
• Unexplained fatigue or dizziness
• Changes in heart rhythm or breathing
• Signs of dehydration, such as extreme thirst or dark urine
• Uncertainty about the correct dosage or the simultaneous use of other medicines

Regular contact with a doctor is not only intended for solving problems, but also for evaluating progress. Based on the results and the health situation, a doctor can assess whether the treatment should be continued, adjusted, or phased out.
