Hiccups usually stop within a few minutes to a few hours. Hiccups that last longer than 48 hours are called persistent hiccups. Hiccups that last longer than a month are called intractable hiccups. While very rare, intractable hiccups can cause exhaustion, lack of sleep, and weight loss.
Gap junctions. Gap junctions. connections between cells which allow passage of small molecules and electric current. Gap junctions were first described anatomically as regions of close apposition between cells with a narrow (1-2 nm) gap between cell membranes. The variety in the properties of gap junctions is reflected in the number of connexins, the family of proteins which form the junctions.

An electrical synapse is a mechanical and electrical conductive link between two neighboring neurons that is formed at a narrow gap between the pre-and postsynaptic neurons known as a gap junction.t gap junctions, such cells approach within about 3.5 nm of each other, a much shorter distance than the 20- to 40-nanometer distance that separates cells at chemical synapse. In many animals, electrical synapse-based systems co-exist with chemical synapses.
