Factors that can trigger attacks include rest after exercise, potassium-rich foods such as bananas and potatoes, stress, fatigue, alcohol, pregnancy, exposure to hot or cold temperatures, certain medications, and periods without food (fasting). [ghr.nlm.nih.gov]

Myopathy : This form is characterized by permanent muscle weakness, fatigue, and pain. More than 74 percent of older people with hypoPP experience myopathy. [healthline.com]

The paralytic form is more common, causing randomly spaced attacks (or episodes) of weakness which range from mild (which feels like fatigue) to flaccid (rag-doll-type) paralysis triggered by a fall in serum potassium. [hkpp.org]

Attacks may be provoked by stress such as a viral illness or fatigue, or certain medications such as beta-agonists, insulin or steroids. A perturbation of sodium and calcium ion channels results in low potassium levels and muscle dysfunction [ 2 ]. [casesjournal.biomedcentral.com]

Also, alterations of serum osmolarity, pH, and hypothermia-induced muscle shivering and mechanical stimuli can exacerbate the myotonic reaction. [ncbi.nlm.nih.gov]

IEM is characterized by intermittent burning pain and skin redness in hands and feet. This condition is usually triggered by warmth or exercise 48. Therefore, P1308L in the neuronal Nav1.7 shares some of the triggers with P1158S in skeletal muscles. [doi.org]
