In astrology, a "nadi dosha" is said to occur when the planets associated with the nadis (the main arteries of the body) are in close alignment. This is said to cause problems in the flow of energy and can lead to health issues.

There are said to be three main nadis in the body: the ida, the pingala, and the sushumna. Each nadi is associated with a different planet: the ida with the moon, the pingala with the sun, and the sushumna with Jupiter.

When the planets associated with the nadis are in close alignment, it is said to cause a nadi dosha. This can be remedied by performing certain rituals, such as chanting mantras or doing yoga.
