Name two conditions that present with deep and fast breathing?

1. Hyperventilation syndrome: This condition is characterized by rapid and deep breathing, often caused by anxiety or panic attacks. It can lead to symptoms such as dizziness, chest pain, and tingling in the extremities.

2. Diabetic ketoacidosis (DKA): DKA is a serious complication of diabetes that occurs when the body produces high levels of ketones due to a lack of insulin. One of the symptoms of DKA is rapid and deep breathing, known as Kussmaul breathing. Other symptoms include fruity-smelling breath, confusion, and abdominal pain.
