Loss of appetite for a day or two may mean nothing. But if you’ve already had several weeks or months without appetite, you need to see a doctor to rule out any physical or mental problems. Not eating properly can lead to weight loss, frailty, mobility difficulties, and even, in severe cases, death from malnutrition (1,2).
Here we tell you about its possible causes and how it relates to menopause. You will also find some recommendations to improve your appetite.
Possible causes of loss of appetite
Lack of appetite may be due to physical conditions or even mental problems. The main causes are (1,2):
- Advanced age, because of slower bowel movements.
- Inherited conditions affecting the lungs and pancreas.
- Use of some medications that suppress appetite.
- Drinking too much alcohol or taking drugs.
- Getting infections such as a cold, flu, or stomach virus.
- Illnesses that make breathing difficult, such as asthma.
- Stomach problems such as acid reflux, stomach pain, constipation, or indigestion.
- Loss of smell, which can make food less appealing.
- Problems with the mouth or teeth that make it difficult to swallow or chew food.
- Having undergone surgery or being hospitalised.
- Diseases of the digestive system such as colitis, gallstones, and irritable bowel syndrome.
- Hormonal problems such as diabetes or hypothyroidism.
- Some cancers or their treatments.
In addition, feeling stressed, anxious, or sad can also lead to loss of appetite. In this sense, mental illnesses such as depression, anxiety, and eating disorders such as anorexia nervosa can have an impact on food intake (2).
Relationship to menopause
To understand the relationship between loss of appetite and menopause it is important to look at this period of life from all angles (3).
In principle, the fall in oestrogen levels does not produce a lack of appetite. On the contrary, there may be an increase in food intake and a tendency to become overweight. However, menopausal women may experience mood changes that lead to poor appetite. They may also have age-related slower digestion and may be taking certain appetite altering medications (2,3).
Not eating for a long time can be bad for your health. If you suddenly don’t want to eat and you don’t know why, it is important to talk to your doctor. Some warning signs are (4):
- You have a loss of appetite for more than a week.
- You lose a lot of weight all at once.
- You feel tired, weak, nauseous, have a racing heart or are irritable.
Recommendations for coping with loss of appetite
Here are some tips to help you stimulate your appetite and eat well during menopause (5,6):
- Don’t skip meals, set a fixed eating schedule and stick to it.
- Choose more nutritious foods such as fruits and vegetables with different vitamins and minerals.
- Eat more food on days when you feel like eating more.
