The answer is Glycogenolysis
When we are hungry or skipped a meal our  glucagon, <span>an hormones</span> that regulates blood-sugar levels, is released to avoid glucose levels in the blood to decrease to a risky value.
Glucagon makes the liver, but also the muscle, to breakdown accumulated glucose called glycogen into glucose to increase blood-sugar levels. This process is called Glycogenolysis and can also be  stimulated by an increase in epinephrine during  fight-or-flight responses.
        
                    
             
        
        
        
Shortness of breath or difficulty in breathing is also called dyspnea and can be acute or chronic. It has various causes, but mainly can be caused by a problem in the heart or the lungs. Since your heart and lungs are both involved in the transportation of the oxygen to the tissues and the removal of carbon dioxide, any problems occurring to these systems can affect breathing. 
B-type Natriuretic Peptide (BNP) reflect the systolic and diastolic activity of the heart and its blood levels can show any heart failure. A BNP test and can help the nurse decide whether the cause of the dyspnea is a heart failure or some respiratory problem.
