18. Chills

People may also experience chills accompanying the fever associated with gallbladder infection. Inflammation of the gallbladder or acute cholangitis results from the abnormally high numbers of bacteria accumulating inside a blocked gallbladder. Because of this, fever develops, often followed by chills.

Shivering, or chills, is part of the body’s natural response to infection, raising its core temperature through the rapid contraction and relaxation of its muscles, producing the heat needed to battle harmful bacteria that cause illness.
