But if the pants pinch, even though you have not changed diet and habits, may be a drug behind it. Because some drugs can cause a weight gain as a side effect. We explain how it can lead to an increase in weight through medication and which tablets can make you fat.
Why is weight gain due to medication?
Various mechanisms may cause weight gain when taking medication: An increased appetite as a side effect often leads to increased calorie intake.
In addition, some drugs may cause dry mouth or increased thirst. Therefore, if more calorie-containing drinks are taken up, this can promote weight gain.
Furthermore, some medicines can lead to water retention, which increases the weight. Also, a direct effect of certain drugs on the energy metabolism can affect the weight. Often, however, the exact cause of the weight gain is not clear.
Which medications make you fat?
Medication works differently in every person - the occurrence of side effects is individually different and also depends on the dosage. Also, interactions with other drugs may play a role.
A List of tablets that make you fat therefore does not exist. However, there are some groups of drugs where weight gain is often observed. These include, among others:
- cortisone-like active ingredients (glucocorticoids)
- Medicines for mental illnesses (antidepressants and antipsychotics)
- Insulin and other medicines for diabetes

- Medicines for epilepsy (anticonvulsants)
- High blood pressure medicines like beta blockers

In long-term use, cortisone also promotes muscle breakdown, which reduces energy expenditure. However, these side effects usually only occur when taking cortisone-containing tablets. In a local application - such as a spray in asthma - the risk of weight gain is very low.
Antidepressants affect appetite
Among the drugs against depression, the so-called tricyclic and tetracyclic antidepressants as well as some serotonin uptake inhibitors have an appetite-increasing effect. The active ingredients fluoxetine and bupropion, however, inhibit the appetite and can lead to a loss of weight.
Lithium, which is used primarily in manic depression, leads to a particularly frequent increase in weight. An influence on the carbohydrate and fat metabolism, thyroid function and appetite is suspected.
Valproate and carbamazepine are used in both manic depression and epilepsy and can also increase weight.

Diabetics who inject insulin often struggle with their weight. Because insulin inhibits fat burning and promotes the buildup of fat deposits. But some anti-diabetes medications can also lead to weight gain. These include the so-called sulfonylureas such as glibenclamide as well as active compounds with the ending -glinide or -glitazone.
Weight gain from diabetes medications is often particularly problematic as many type 2 diabetics are already overweight and every extra kilo has a negative impact on the disease.
Possible alternatives are the so-called incretin mimetics and the active ingredient metformin, which promote weight loss. It is best to ask your doctor.
Thyroid medications affect metabolism
Thyroid hormones play a crucial role in energy metabolism. When given as a drug in hypothyroidism, they can lead to weight loss. However, recently reduced doses may explain an increase in weight.
So-called antithyroid drugs, which are given in hyperthyroidism, however, inhibit thyroid function and can thereby cause an increase in weight.
It is best to tell your doctor if you are experiencing a weight change while taking thyroid medications.
