Here are some yoga asanas (poses) that might help:

1. Cat-Cow Pose (Marjaryasana-Bitilasana): This dynamic movement helps massage the abdominal organs and can stimulate digestion. Start on your hands and knees, alternate between arching your back (cow) and rounding it (cat).

2. Child's Pose (Balasana): A gentle pose that can help relax the body and mind. It also gently stretches the lower back and can aid in digestion.

3. Seated Forward Bend (Paschimottanasana): This pose helps stretch the spine and abdominal muscles, which may improve digestion. Sit with your legs extended and reach forward towards your toes.

4. Legs-Up-the-Wall Pose (Viparita Karani): This restorative pose helps calm the nervous system and can reduce stress. Lie on your back with your legs extended up a wall, and relax in this position for several minutes.

5. Supine Twist (Supta Matsyendrasana): This gentle twist can help stimulate digestion and relieve gas and bloating. Lie on your back, draw one knee across your body, and gently twist your torso.

6. Wind-Relieving Pose (Pavanamuktasana): Specifically designed to release gas and improve digestion. Lie on your back, bring your knees towards your chest, and hug them in.

7. Bridge Pose (Setu Bandhasana): This pose strengthens the back and can help relieve constipation and digestive discomfort. Lie on your back, bend your knees, and lift your hips towards the ceiling.

When practicing these poses, listen to your body and avoid any movements that cause discomfort. It’s also important to complement yoga with a balanced diet and proper hydration. If you have specific health concerns or conditions, consulting a healthcare professional before starting any new exercise routine is a good idea.
