Your changing body

Weight is the obvious change and the least interesting one. Your centre of gravity shifts, which is why backache is so common and why shoes you liked stop working. Ligaments loosen. Sleep gets harder to arrange, and side-sleeping with a pillow between the knees helps more than most advice. Skin changes, and so does hair. Heartburn arrives for many people in the second half. Almost all of it is ordinary, and almost all of it passes. What is not ordinary is sudden swelling, severe headache, or vision changes, which need a call.
