Detailed Answer:
Hi,
Thanks for choosing HealthcareMagic for your query.
Have gone through your details and i appreciate your concerns.
As per your query my dear patient feeling gas bloating and weight gain are not very common with probiotics. Why?

See probiotic's are nothing but good bacteria's of gut.In our gut there is a equilibrium of good and bad bacteria's.When this equilibrium is disturbed there arises a number of problems with a person's digestion so to help to replete the gut flora back to normal again we use probiotics.
Good bacteria's florishe's in our gut these bacteria play a vital role in digestion and absorption of food.As per researches even minor disturbances in gut microflora can lead to significant changes in gut function, including gas production.
If this microbiota is disturbed food is improperly fermented causing production of large amount of gases in gut leading to severe flatulence and bloating.Hence disturbed microbiota instead of probiotic can be responsible for it.In old patient mobility of intestines iscompromised leading to accumulation of large amount of gases in intestines.As peristaltic moments are week gas accumulates in intestines.


-Small Intestinal Bacterial Overgrowth can be a reason of severe flatulence .
Small intestinal bacterial overgrowth (SIBO) refers to a condition in which abnormally large numbers of bacteria are present in the small intestine, and the types of bacteria in the small intestine resemble more the bacteria of the colon than the small intestines causing improper and disturbed food digestion.


Tests suggested-
Small bowel imaging and a gastric-emptying scan.

As per your query however i would advice you to take VSL#3 once daily its an over the counter and very safe probiotic.
Hope i was helpful.
Wish you a great day ahead.
Regards.
