Factors That Can Affect Ingestive Behaviour: Drugs and Medications



Continuing with citations from my article in Obesity Reviews on an aeteological framework for assessing obesity, we now turn to the some of the factors that can affect ingestive behaviour, this post focusses on medications:

Medications and Drugs That Affect Hunger and Appetite

A wide range of medications and illicit drugs can promote hunger and appetite. These include some oral anti‐diabetic agents, antidepressants, atypical antipsychotics, anticonvulsants, certain hormonal preparations including corticosteroids and oral contraceptives, as well as the medicinal and recreational use of marihuana. Alcohol and other mind‐altering drugs can also promote over‐eating by increasing appetite, reducing dietary restraint and promoting disinhibition. Patients presenting with weight gain and obesity need a careful review of their medication and substance abuse history.

Commentary: Obviously this a complex topic as the number of medications and recreational substances that can affect appetite and eating behaviour is long. Nevertheless, assessing the possibility that a change in appetite and weight gain are due to this factor is an essential part of clinical assessment.
