Its a pretty huge number if you look at the total number of outbound tourists from Bangladesh. That number was around 1.5 million in 2013.
Furthermore its a pretty big number if you reduce the cohort to people that can actually afford to indulge in such travel.
And you are saying all or most of this is predicated on "medical" reasons. If true you are basically asserting Bangladesh deserves to be in the least developed category since any country that can't provide health services to 1 million of its citizens (who have the means and income to travel to another country) is definitely not a generic developing country.
Conversely if anyone asserts these tourists are not all medical but only some are, that means a good number visit for other reasons (business, pleasure, family visit etc).
You can't hold up both sides together basically and expect it to fly.
Well your compatriot brought it up, so take it up with him. "Horlicks" here like I said was used as a generic reference to consumer goods anyway. Its pointless to debate which ones are in large demand and which ones aren't. His general assertion is that Bangladeshis consume "way too much" Indian produced "garbage".
Importing consumer goods in general from India yes (again Horlicks is just one small example). The split between raw commodity to processed goods (which include labour margins) is about 60 - 40....so its not like Bangladesh imports near 100% only raw goods from India....About 40% is a significant percentage and it explains why the trade disparity is so high.

I am referring to table A.8 on page 28.
Its a 57/43% split by primary commodity/manufactured in the Indian exports to Bangladesh...further broken down by low, med and high skill manufacturing component.
If you have a later source of the current composition in trade, please post it.
In 2013-2014 India exported around 6 billion USD to Bangladesh....and imported about 456 million. Thats terms of trade overall at about 13 to 1.
Look at the composition of the items:
http://www.dhakachamber.com/Bilateral/India-Bangladesh Bilateral Trade Statistics.pdf
Some examples of what Bangladesh imported from India and the amounts that year:
Vehicles other than railway or tramway rolling- stock and parts and accessories thereof (497.7 million)
Nuclear reactor, boilers, machinery and mechanical appliances, parts thereof (278.7 million);
Iron and steel (213.9 million)
Organic chemicals (160.8 million)
;Mineral fuels, mineral oils and products of their distillation, bituminous substances, mineral waxes (141.7 million);
Plastics and articles thereof (138.3 million)
Electrical machinery and equipment and parts thereof, sound recorders and reproducers, television image and sound recorders and reproducers and parts and accessories of such articles (114.1 million);
and theres more further down the list....certainly looks like the 60/40 ratio is about the same. Also compare with the composition of things Bangladesh exported to India that year.
So the TOTAL amount we import from Bangladesh is more than financed by JUST the vehicles we export to you. Everything else is on top of that. Assuming by 2018 India exports around 9.2 billion and imports 800 million (going by current trends)....that means you will be importing around 3.7 billion worth of industrial/manufactured goods from us (the rest 5.5 billion is agri, cotton, primary ores etc) and exporting around 600 million of primary products (raw jute, agri) and 200 million manufactured (mostly RMG) in return.
