Could Your Medications Be Affecting Your Appetite?

If food has stopped tasting the way it used to, or you simply are not feeling hungry, your medications may be part of the reason. Many older New Zealanders take several prescriptions at once, and changes in appetite are a common side effect that often goes unmentioned at appointments.

How Medications Can Change Your Appetite

Some medicines can dull your appetite, while others can make you hungrier than usual. Certain pain relief, antibiotics, heart medicines, antidepressants and treatments for conditions such as diabetes or Parkinson’s disease are known to influence how much we want to eat. Others may cause nausea, constipation or a dry mouth, which can make meals feel unappealing.

Taste and Smell Matter Too

Some medications alter taste, leaving a metallic or bitter flavour in the mouth. Because our sense of smell and taste naturally fade with age, this can make favourite foods seem bland or strange. Over time, eating less can lead to unwanted weight loss, low energy, muscle weakness and a higher risk of falls.

Simple Ways to Support Your Appetite

Small changes can help. Try eating smaller, more frequent meals rather than three large ones, and choose nourishing snacks such as yoghurt, cheese, nuts or fruit. Adding herbs, lemon juice or a little spice can lift flavour. Staying hydrated and sharing meals with family or friends often makes eating more enjoyable too. A short walk before a meal may also help stir up an appetite.

When to Talk to Your GP or Pharmacist

Never stop or change a medication without professional advice, even if you suspect it is affecting your appetite. Instead, make a note of when your appetite changed and which medicines you take, including over-the-counter products and supplements. Your GP, practice nurse or community pharmacist can review your list, check for interactions and suggest adjustments where suitable. Ask whether a medicines review is available to you.
