What is the meaning of sinking sensation?

A sinking sensation is a feeling of being suddenly very weak or faint, as if the ground or floor beneath you is moving away from you and going lower and lower. This sensation is typically accompanied by a feeling of dizziness, nausea, and stomach discomfort. It can be a sign of several underlying medical conditions, such as low blood pressure, hypoglycemia, dehydration, anxiety, or panic disorder. It can also be a symptom of a heart attack, stroke, or other serious medical condition. If you experience a sinking sensation, it is important to consult with a doctor to rule out any underlying health problems.
