👉 Underventilating is a medical condition that occurs when someone does not breathe as deeply and forcefully as they should. This can cause breathing difficulties, including shortness of breath, chest pain, or a feeling of suffocation. In some cases, underventilating may be due to underlying health conditions such as asthma, chronic obstructive pulmonary disease (COPD), heart failure, or certain medications. It is important for individuals with underventilating symptoms to seek medical attention
