What could cause throat swelling that worsens at night?

Throat swelling that gets worse at night can be caused by several conditions. One possible cause is snoring-induced vibratory angioedema, where the vibrations from snoring lead to swelling in the throat area. This happens because the tissues in the throat vibrate during snoring, causing them to become swollen over time.

Another potential cause is angioedema, which is a sudden swelling under the skin. It can occur due to an allergic reaction, certain medications, or even without a known cause. Angioedema can be serious and may require immediate medical attention, especially if it affects breathing.

Additionally, conditions like Ludwig's angina can cause throat swelling. Ludwig's angina is a serious infection that affects the floor of the mouth and can lead to swelling that might worsen at night due to lying down, which can increase pressure in the area.

If you or someone you know is experiencing throat swelling, especially if it worsens at night, it is important to seek medical evaluation to determine the cause and receive appropriate treatment.
