Hiccups occur when a spasm makes the diaphragm contract, a breath of air is brought quickly into the body and is just as quickly stopped by the vocal cords. Although common, hiccups can be considered more serious if they are persistent.

    Causes
  1. Drinking alcohol, eating a lot of food in a shot amount of time, smoking, swallowing an excess amount of air and stress are some of the typical causes of hiccups.
    2. Types
  2. Normal hiccups will go away either on their own or with home remedies within a few hours at most. If they last longer than 48 hours, they are considered persistent hiccups. Those that go on for longer than a month are known as intractable hiccups.
    3. Effects
  3. Normal and persistent hiccups rarely cause any negative side effects. Intractable hiccups can lead to weight loss, sleeplessness and exhaustion.
    4. Underlying Causes
  4. Persistent and intractable hiccups can be symptoms of more serious issues, including metabolic problems, central nervous system issues, nerve injury and mental health problems. They also can occur following surgery and anesthesia.
