Euphorbia lactea. The lateral growths are branches.

It looks like it could use more light! Is it inside or outside? What is your general location or plant zone?

Light is the primary determinant of the thickness of the Euphorbia stems. Indoor light, even in a sunny window, is not nearly as intense as outdoor light, so you can expect that yours will continue to grow mostly taller rather than fatter.

I have seen Euphorbias (and other species) develop much thicker stems on top when they are moved to much stronger light. It is the available light at the time a particular portion of the stem is emerging that will determine thickness. In other words, even if you were to move yours outside, the thinner lower stem would remain that way while the new growth stem on top would be much thicker.

The best solution for dealing with the top-heaviness is to prune the tall stems back. Such pruning will not affect the health of the plant or discourage healthy new growth. It will simply keep the plant at a more manageable height. Moving it to a larger pot will definitely NOT help with the top-heaviness.
