Plants were never meant to be indoors. House plants are considered long term perishables. That doesn't mean they are unable to thrive and live a long time and be beautiful in your home; depending on the plant, environment, soil, chemicals, watering habits and the amount of light this plant receives.
Just by putting houseplants outside on a covered porch (no direct sun) during the dependable summer months allows indoor plants to get more light than indoors and will be able to make extra food to get it through the winters...this makes your indoor plants last longer and thrive far better than continued indoor habitat.
Getting light from the side will promote only those leaves on the side as those leaves getting the light are making food for the plant. Plants are into efficiency and will get rid of leaves that are NOT making enough food in relation to the leaf's own maintenance needs. Other leaves that are making the food over and above their maintenance levels will be promoted and the leaves not getting enough light will be 'fired' or at least be put on lowered salary. Yes, rotating is essential if you want a more symmetrical plant.
Need pictures and more information such as your maintenance habits, N, S, E or West facing window. This plant if Bamboo is correct doesn't need LOTS AND LOTS of light but getting lots of light will cause it to grow and color far better. That back side needs to get some of that yummy light so the entire plant will grow evenly.
If this was a plant that needed lots and lots of light rotating would mean decreasing light to the sides not facing the light within the rotation sequence. But this plant will do just fine rotating it, possibly every other day 1/4 or 90 degree turn versus 180 degrees. If you go on vacation, a few weeks, a month, no big deal. You won't be harnessed to this plant that closely at all.
Watch the growth of roots and the size of pot. More light, more food, more growth and more growth of roots. With a picture we'll be able to tell you whether it needs to be re potted (with potting soil, no gravel at the bottom).
What are your maintenance habits to include water, type of water and fertilizer?
