my dear... diabetes - good question, correct, but no, I have not diabetes... I know that it is one from some reasons of my amotio retinae, but no, also myopia, diabetes, genetic, mechanical damage,.. in my case it is idiopatia - unknown reasons.... maybe hypothyreosis has some influence....
Please try another pranayam along with the previous two .This one is called Kapalbhati:-‘Kapal’ means forehead and ‘Bhati’ means light. Hence, Kapal-Bhati refers to that exercise which makes the forehead luminous and lustrous. Kapal-Bhati Pranayama makes its Sadhak’s head luminous. in Kapal-Bhati more attention is to be given to the act of forceful Recak(exhalation- breathing out). In Kapal-Bhati, the Puraka(inhalation- breathing in) is to be done with normal, usual force but the Recak has to be done with as much of force as is at your command. In doing so, the abdominal area, also makes inward and outward movements and considerable force is applied to the Manipura,Svadhisthana and Muladhara Chakra. This Pranayama should easily be done for five minutes. In short, breathe in normally and breathe out forcefully, so as to influence the organs of the abdominal area. Persons suffering from acute and chronic diseases must practice if for 15 minutes or more as per the capability.
For Hypothyroidism try Anulom bilom pranayam:- Method to close the nostrils:
To be done by closing the nostrils one after another, close the right nostril by the right hand thumb, and likewise close the left nostril by the 2nd and 3rd fingers (Madhyama and Anamika) fingers keep the palm of the hand in front just above the Nose.
Prana breathed in through left nostril represents energy of the moon, which symbolizes peace, and has a cooling effect. Hence for purification of Nadis, beginning of this Pranayama has to be made by the left nostril. Close the right side nostril with the right hand thumb. Inhale slowly through the left nostril till the lungs are filled. Then close the left nostril with the second and third fingers. Open the right nostril and exhale through it. Repeat this exercise slowly in the beginning, and with practice, increase the speed. When you are able to practice this exercise for a long time, inhale with as much force as is possible for you, then exhale also forcefully. This practice of inhalation and exhalation alternatively through the right and left nostril, as indicated above with force, should be done for 3 minutes. If you feel tired, rest for sometimes and resume. Regular practice will enable you to do this Pranayama for 10 minutes. After some practice being established, this Pranayama should be done for 5 to 10 minutes daily, depending upon one’s capacity. However, in summer season it should be done for duration starting from 3 minutes and up to a maximum of 5 minutes. If you practice this Pranayama for five minutes regularly on a daily basis, the coiled energy called Kundalini Shakti lying in the Muladhar Chakra begins to awaken.This is known as Kundalini Jagran.. While doing this Pranayama, mentally repeat the mantra “OM” so the mind becomes fit for meditation.
For vertigo try Bhramri pranayam:-Breathe in till your lungs are full of air. Close your ears with both the thumbs and eyes with the middle fingers of your hands on respective sides with little pressure. Press forehead with both the index fingers lightly. Close both the eyes. Then press eyes and nose bridge from the sides with the remaining fingers. Concentrate your mind on Ajna Chakra (between eye-brows) . Close your mouth. Begin slowly exhaling, making humming sound of a bee, while reciting “OM” mentally. Repeat the exercise 11 to 21 times according to your capacity.
