Before I proceed with the discussion regarding astrology and health issues, I must first issue a disclaimer. Astrologers are not doctors. If you have a health problem, make a beeline to your personal physician and forget about astrology for the time being. Having said that, certain planets do seem to have rulership over certain parts of the body, and certain planetary constellations and aspects appear more likely than others to cause illness.
I’ll give you a few examples of planets and a few of the areas of the body they govern:
Sun: heart, upper back, right eye in males, left eye in females
Moon: breasts, stomach, left eye in males, right eye in females
Mercury: lungs, solar plexus, arms, hands, tongue, nervous system, sense of sight
Venus: throat, kidneys, skin, sense of touch, lower part of back, buttocks
Mars: muscular system, bladder, head, face, sense of taste
We generally look at one’s sixth house and its ruler with regard to health issues. In a natal chart, the Ascendant, the Sun, the Moon, Saturn, and Mars and their conditions/situations are also important. A chart must be looked at in an holistic manner for a proper analysis, however. If Saturn is transiting your sixth house, it’s time to get serious and focus on health issues. You can solidify your health and your body, so why not join the gym. Ignore your health during this period and you are likely to be or get into trouble healthwise. If Jupiter is transiting your sixth house, your health is likely to be quite good. However, you might also be prone to gaining weight. The positive effects of Jupiter are sometimes limited. Jupiter has healing powers, but the planet also expands whatever it touches. If it touches a tumor in your body and expands it, that is not such a good thing. If you have a health issue while Neptune is transiting your sixth house, it may be difficult to pinpoint exactly what is wrong or what is the problem.
All of the signs govern certain areas of the body and are prone to some health issues. If you’d like to know more about that, check out this site for more information.
