Why do I experience constipation even after taking necessary medications?

Hello doctor,

I am a yoga and meditation teacher. I lead a healthy life by exercising and having healthy home-cooked food (I will also include adequate spicy foods). I am following a diet according to what the ayurveda doctors have advised. I take a tablet of Dhootapapeshwar Triphala Guggul every day and try to take it in the morning with a glass of hot water, which I always have in the morning before drinking green tea. Still, I am constipated, especially when the weather gets too hot for my system and when I travel away to different places, I cannot cook my food. So it appears that, in my case, constipation is due to neurological disorders. I am highly vata and highly sensitive since I have lived a stressful life that started in the hands of a young mother who mishandled and verbally abused me from a very young age. Later, I started learning aikido, yoga, and tai chi chuan and started teaching these disciplines. My question is that since the cause of my problem is neurological, would you advise me to take Panchasakar Churna, Arogyavardhini Vati, and syrup Abhayarishtam? I also take a small spoon of Ashwagandha Churna in the morning along with my breakfast; should I take some of it at night too?

I would appreciate any help to get out of this ongoing ordeal of constipation which brings anxious thoughts to the point of suicide at times.

Thank you.
