hypoosmolality; hyposmosis
Medical/biological term for a state where the osmotic pressure of a body fluid is lower than normal. Used in clinical contexts such as hyponatremia or fluid balance disorders.
Hypoosmolar hyponatremia occurs due to a decrease in serum sodium concentration.
Because this patient is in a hypoosmolar state, careful fluid management is necessary.
浸透圧 is osmotic pressure in general, while 低浸透圧 specifically refers to abnormally low osmotic pressure.
高浸透圧 is the opposite condition: hyperosmolality, where osmotic pressure is higher than normal.
Compound of 低 (てい, 'low') + 浸透圧 (しんとうあつ, 'osmotic pressure'). A straightforward technical term formed from standard Sino-Japanese elements.
