Which of the following is a symptom of asthma?

Chest tightness is a notable symptom of asthma. This sensation occurs because the airways become inflamed and narrowed during an asthma attack, making it difficult for air to flow in and out of the lungs. This can lead to discomfort or pain in the chest, often described as a feeling of pressure or tightness.

Asthma symptoms can also include wheezing, coughing, and shortness of breath, particularly during physical activity or at night. Recognizing chest tightness as a key indicator of an impending asthma episode is crucial for managing the condition effectively, as it often prompts individuals to use their rescue inhalers or seek additional medical help.

Other options, such as weight gain and increased appetite, are not typically associated with asthma symptoms and might indicate other health concerns. Loss of smell is more characteristic of sinus or nasal issues rather than being directly linked to asthma. Thus, chest tightness stands out as a primary and significant symptom of this respiratory condition.
