3.Since at the age of 6yrs ,i have been facing constipation problem. Approx. 8 years before ,a Gastroenterologist specialist doctor
informed me that i have IBS - Constipation problem.
Long time history Difficulty in morning bowel movement.I won't feel pressure for bowels in the morning.
I need to take 2-3 glass of warm water daily to get some pressure.
Overall, it delays and disturbs a lot my daily routine.I need usually 30-45 mins to come out of the toilet.
I NEED TO START MY DAY AS EARLY AS POSSIBLE ,TARGETING 4 AM.
3.a)If i eat leafy vegetable then i see parts of those in stool.If i eat beet root in good quantity ,the color of stool changes.
Seems digestion is not happening properly.
3.b) If constipation persists for long time,may be many weeks ,then sexual related health again gets impacted ,if with some medicines if it had been improved a little bit.
3.c) Gas formation more happens after 5 pm ,evening time specially.Mostly gas is odourless.Many times feels gas is struck in my stomach.
Very quickly gets acidity ,heart burn.Specially not able to tolerate green chilly ,it gives strong stomach heat and heart burn.
Before sleep at night ,if i drink 1 glass or somewhat water more ,i gives me straight way acidity.I couldn't able to sleep with the support of right shoulder.
Black pepper power ,doesn't give me acidity.Red chilly in moderation is still okay for me.
ALWAYS FEEL HEAT IN THE STOMACH. I RARELY GET HUNGER ,MAY BE 1 OR 2 TIME IN A 50 DAYS.
Digestion is slow.
If i eat late in the afternoon like around 3 pm than i feel too much laziness and like to sleep.
4.Due to studies and job pressure,my physical activities reduced a lot in last 24 years.Now almost none.
If try to go for jogging ,i get tired within 5 mins.I feel kind of stiffness in my legs.I feel breathing also too much.
5.My chest muscles and buttocks also quite soft ,i guess it's usually not the case with mens
even though i have put up some weights in last couple of years.
Last year i tested for testestrone hormone .It was in near minimum range.
