What type of medication can cause side effects such as headache and weight gain?

Prednisolone is a synthetic corticosteroid that is widely used to treat various inflammatory conditions and autoimmune disorders. One of the well-documented side effects of prednisolone is weight gain, which can occur due to increased appetite and fluid retention. Additionally, corticosteroids like prednisolone can influence the metabolism of carbohydrates, fats, and proteins, leading to further weight gain.

Headaches can also be a side effect of corticosteroids. While the precise mechanism isn't always clear, it may be related to changes in fluid balance, blood pressure, or hormonal fluctuations caused by the medication.

As a systemic corticosteroid, prednisolone affects multiple systems in the body, which contributes to its potential for a variety of side effects, including those mentioned. Other medications, like inhaled corticosteroids, can also have side effects, but they are generally less pronounced in terms of weight gain compared to systemic corticosteroids.
