## Core Concept
Inhalational steroids, also known as inhaled corticosteroids (ICS), are a cornerstone in the management of chronic respiratory diseases such as asthma and chronic obstructive pulmonary disease (COPD). They work locally in the lungs to reduce inflammation. However, like all medications, they can have systemic and local side effects due to their mechanism of action and potential systemic absorption.

## Why the Correct Answer is Right
The correct answer, , implies that one of the listed complications is a known side effect of inhalational steroids. Inhalational steroids can cause local side effects such as **dysphonia** (voice changes), **cough**, and **oropharyngeal candidiasis** (thrush) due to direct deposition of the drug in the mouth and throat. Systemic absorption can lead to ** adrenal suppression**, **growth retardation** in children, and **osteoporosis** with long-term use, although these are less common with newer, more potent drugs that are designed for local action.

- **Option B:** [Not provided, assumed incorrect based on question structure]
- **Option C:** [Not provided, assumed incorrect based on question structure]

## Clinical Pearl / High-Yield Fact
A key clinical pearl is that the risk of systemic side effects can be minimized by using **spacer devices** or **inhalation chambers** with a **valved holding chamber**, which helps to reduce oropharyngeal deposition and thus systemic absorption. Also, remember that inhaled steroids are crucial for long-term control of asthma and are recommended even for mild persistent asthma.

## Correct Answer Line
**Correct Answer: D.**
