It also shares practical measures to find relief confidently.

Pregatips
The final months of pregnancy feel completely different from the early stages because of the changes in your body. You may become more sensitive to movement and pressure. You may experience intense pain around your ribs when you laugh, sneeze, or hiccup.

But this is a normal response to the physical changes, though it can feel uncomfortable. Knowing the reasons can reduce unnecessary worry and lead to a comfortable pregnancy.

What Are Rib Stitches During Pregnancy

Rib stitches are sharp pains that you may feel along the sides of your rib cage. They last for only a few seconds or a few minutes. But these pains mostly occur when you make quick movements, such as laughing, coughing, or hiccupping, or when you change positions.

The pain can be intense in the late pregnancy, but it is related to muscles or nerves rather than a serious medical problem.

Why Are Rib Stitches More Common in Late Pregnancy

You will notice the pain in your ribs around 28 weeks, when you are well into the last trimester. It occurs because your baby grows rapidly by this time. So, your uterus also expands upward and pushes against the diaphragm and ribs.

Your uterus can grow by almost 5 times its original size in the late pregnancy. It leaves less room for your organs and muscles to move, increasing pressure on your ribcage.

How Do Hiccups Trigger Rib Pain

Hiccups cause sudden contractions of your diaphragm, which is the muscle just below your lungs. In late pregnancy, your diaphragm is already pushed upward due to your growing uterus. These quick contractions can lead to the following changes:

  • Stretch already tight muscles
  • Press nerves near the ribs
  • Trigger spasms in the weak abdominal muscles
This combination results in a sharp rib stitch, even if only briefly.

Why Does Laughing Cause Sharp Pain Near Your Ribs

Laughing involves movements of your chest, diaphragm, and abdominal muscles. These muscles are already stretched and under strain during pregnancy. When you laugh, the following things happen in your body:

  • Your abdominal muscles tighten suddenly
  • Your rib cage expands quickly
  • Pressure shifts inside your chest and abdomen

Does Baby’s Position Play a Role in Rib Stitches

Your baby’s position also plays a role in the pain. They reach 2.5 to 3.5 kilograms by full term, so they may push feet, elbows, or knees into your ribs. If your baby is positioned high or stretches upward, you may feel the following sensation:

  • Sharp pokes under the ribs
  • Ongoing tenderness on one side
  • Pain that worsens when you move or laugh
So, you may feel uncomfortable even with small movements.

Are Rib Stitches a Sign of Something Serious

Rib stitches from hiccups or laughter are not worrisome in most cases. They are caused by muscle stretching, nerve compression, or limited space in your abdomen. So, speak to your doctor if you notice the following signs:

  • Severe and constant pain with fever
  • Linked with breathing difficulty
  • Combined with upper abdominal pain, nausea, or vision changes
These symptoms are also common with gallbladder problems or high blood pressure.

How Can You Relieve Rib Stitches Safely?

  • Adjust Your Posture

Sit upright with good back support because slouching increases pressure on your ribs.

  • Change Positions Slowly

Sudden movements can trigger pain, so move gently when you stand, sit, or turn.

  • Support Your Rib Area

Placing a cushion or folded towel under your ribs may ease pressure while sitting or sleeping.

  • Practice Gentle Stretching

Slow stretches for your side or prenatal yoga can reduce muscle tightness.

  • Control Your Breathing

Deep breathing during laughter or hiccups can reduce sudden muscle contractions.

What Should You Avoid Doing?

  • Avoid sudden movements
  • Do not hold your breath during laughter
  • Limit long periods of poor posture
  • Avoid heavy lifting
You will feel more comfortable with these small adjustments.

What To Do Next: A Simple Checklist

  • Observe when rib pain occurs and what triggers it
  • Maintain an upright posture throughout the day
  • Use pillows for support while resting
  • Practice gentle stretching exercises daily
  • Drink enough fluids to reduce muscle spasms
  • Consult your physician if pain becomes severe
These steps can make your life a little easier during pregnancy.

Emotional and Social Impact: How Can You Cope Better?

Experiencing pain during laughter can be frustrating and emotionally draining. The pain can dampen your mood and may lead to unnecessary worry about enjoying the moment. Share this concern with your partner so they can better support you. Humour, reassurance, and emotional support can ease stress, which, in turn, may reduce muscle tension. Remember, these changes are temporary, as your body prepares for delivery.

Rib stitches during hiccups or laughter in late pregnancy are caused by stretching of the muscles, pressure on the diaphragm, and your baby’s position. They are harmless in most cases, but it is also difficult to ignore the uncomfortable feeling. You can stay more comfortable by taking care of your lifestyle choices during the final weeks of pregnancy.

  2. Will rib pain go away after delivery?
    Most rib pain goes away within weeks after delivery with the decrease in pressure on the diaphragm and ribs.
