Which is a common side effect of hormonal contraceptives?

Hormonal contraceptives often lead to alterations in the body's hormonal balance, which can induce several side effects. Nausea is one of the most common side effects reported by users of these contraceptives. This can occur due to the introduction of synthetic hormones such as estrogen and progestin into the body, which can unsettle the gastrointestinal system, especially during the initial months of usage.

The other effects mentioned, such as increased libido, enhanced energy levels, and improved skin condition, do not commonly occur as side effects. In fact, while some individuals might experience improved skin condition—particularly those who use hormonal contraceptives for conditions like acne—this is not universally true and is not classified as a side effect related to the overall experience of all users. Similarly, increased libido and enhanced energy levels are not typical reactions to hormonal contraceptives and may vary greatly among individuals. This variability signals how nuanced responses to hormonal fluctuations can be over time and across different individuals.
