Postpartum Body Changes: Hair Loss, Night Sweats, Weight and Skin

Your belly and uterus

• Right after birth most people still look a few months pregnant. The uterus shrinks back to near its usual size by about 6 weeks; afterpains during feeds are part of that.
• The skin and muscles take longer, often many months. A belly that stays soft or rounded is normal. See the pelvic floor guide for belly separation.

Night sweats and swelling

• Drenching sweats, especially at night, are common for the first few weeks as hormones drop and the body clears extra fluid. Sleep on a towel, keep a spare shirt nearby and drink water.
• Swelling in the feet and legs can get worse for a few days after birth, then fades over a week or two. Put your feet up and walk a little.
• You'll pee a lot in the first days for the same reason.

Hair loss

• Pregnancy hormones keep hair in its growing phase. After birth, lots of it sheds at once, usually starting around 2-4 months and peaking around 4 months.
• It can look alarming (clumps in the shower, thinner temples) but is temporary. Hair usually returns to normal fullness by about a year.
• Gentle care helps: a volumizing shampoo, a looser hairstyle, a soft brush, an iron-rich diet.
• Shedding that lasts past a year, or comes with exhaustion, feeling hot or cold, a racing heart or big weight changes, is worth a check for thyroid problems or low iron.

Weight

• Many people lose about 10-13 lb (4.5-6 kg) at birth and more in the first weeks as fluid goes.
• After that, slow and steady is best. Getting back toward your pre-pregnancy weight over 6-12 months is a reasonable goal, and some bodies settle somewhere new.
• Breastfeeding burns energy but also makes many people hungry. Gentle, gradual loss (about 1 lb / 0.5 kg a week, once feeding is going well) doesn't usually affect milk supply. Crash diets can.
• See the postpartum nutrition guide.

Skin

• Stretch marks fade from red or purple to silver over months. Creams don't erase them; time does most of the work.
• The dark line on the belly and darker patches on the face (melasma) usually fade within a year. Sunscreen and a hat help.
• Acne, dry skin and skin tags can come and go with hormones.

Other surprises

• Periods: may return within 6-12 weeks if you're not breastfeeding, and much later if you are. You can get pregnant before the first period.
• Feet can stay half a size bigger. Wrists and thumbs can ache from lifting the baby.
• Breasts change size and shape with feeding and again after weaning.
• Feelings about your body can swing. Your body did something big; give it the same patience you'd give a friend.

When to check in

• Mention at your postpartum visit or a later checkup: hair loss past a year, feeling unusually tired, shaky or low, or patches of skin or moles that change.
• Contact your provider soon for a red, swollen, painful leg or fever with breast pain. If you have chest pain or trouble breathing, call 911.
