Yoga for diabetes: a safe routine and what the research shows

Can yoga help with diabetes?

For type 2 diabetes, yes, modestly. Studies that added yoga to normal treatment found that blood sugar and HbA1c, the 3-month average, came down a little more than with treatment alone. The effect is real but small, similar to what you might expect from other regular exercise.

Yoga helps through several routes at once. It is physical activity, which helps muscles take up sugar from the blood. It can lower stress, and stress hormones push blood sugar up. And a regular practice often leads to better sleep, more walking and more careful eating, which matter just as much.

For type 1 diabetes, yoga can be part of staying active and managing stress, but it does not change the need for insulin. The safety checks below apply even more.

What the research says

Two reviews pull together most of the trials.

• Chen and colleagues, 2022Pooled 13 randomised trials in people with type 2 diabetes without complications. Yoga lowered HbA1c by about 0.47 percentage points and also improved fasting sugar and cholesterol. All the programs were short, so long-term effects are not known. Published in Frontiers in Sports and Active Living.
• Kumar and colleagues, 2016An Indian review of 17 randomised trials found that yoga added to standard care improved fasting sugar, after-meal sugar and HbA1c. The authors rated the risk of bias in the trials as high, which means the true effect may be smaller. Published in Complementary Therapies in Medicine.

To put 0.47 in context: if your HbA1c is 8.0 percent, a drop like that would take it to about 7.5. Helpful, but most people still need their medicine to reach their target.

Safety checks before you start

Most people with type 2 diabetes can do gentle yoga safely. These are the checks that matter most.

Low blood sugar

If you take insulin or tablets such as sulfonylureas (glimepiride or gliclazide, for example), exercise can drop your sugar too low. Check your sugar before practice if your doctor has asked you to monitor it, keep glucose tablets, sugar or juice beside your mat, and stop at once if you feel shaky, sweaty, dizzy or confused. Do not practise on an empty stomach if you are prone to lows.

Eyes

If you have diabetic retinopathy, especially the advanced kind, avoid head-down poses such as headstand, shoulder stand and deep forward folds, and avoid straining or holding your breath. These raise pressure in the head and eyes. Ask your eye doctor what is safe.

Feet

Nerve damage can make it hard to feel cuts or blisters. Practise on a clean mat, check your feet after class, and skip poses that put weight on sore or numb parts of the feet. Balance poses are easier near a wall.

Blood pressure and heart

Many people with diabetes also have high blood pressure. Skip breath holding and fast breathing such as Kapalbhati unless your doctor has cleared you, and come out of any pose that makes you breathless.

A 30-minute routine for type 2 diabetes

This routine uses common, beginner-friendly poses, many from the Ministry of Ayush Common Yoga Protocol. Do it 5 days a week, ideally 2 to 3 hours after a meal. Move slowly and breathe through the nose throughout.

1. 5 minutes: looseningNeck turns, shoulder rolls, gentle trunk twists while standing, and knee bends to warm up the joints.
2. 6 minutes: slow Sun Salutation3 to 5 slow rounds of Surya Namaskar. Bend your knees in forward folds and keep your head above your heart if you have eye problems.
3. 6 minutes: standing posesTadasana, Vrikshasana near a wall, Trikonasana and Warrior II. Hold each for 3 to 5 breaths, both sides.
4. 5 minutes: seated and lying posesA seated twist (Vakrasana), Bhujangasana (Cobra), Setu Bandhasana (Bridge) and Pavanamuktasana (knees to chest).
5. 5 minutes: breathingSit in Vajrasana or on a chair and do Anulom Vilom for 3 minutes, then Bhramari, a humming out-breath, for 2 minutes.
6. 3 minutes: restLie flat in Shavasana and let the breath settle. Get up slowly, rolling to one side first.

Breathing and relaxation

Stress raises blood sugar through hormones such as cortisol and adrenaline. Slow breathing and relaxation are the part of yoga most aimed at this, and they are safe for nearly everyone.

• Anulom Vilom, slow alternate nostril breathing, 5 minutes, no breath holding.
• Bhramari, breathing in through the nose and humming on the out-breath, 5 to 7 rounds.
• Longer out-breath, breathing in for 4 counts and out for 6, any time you feel tense.
• Yoga Nidra or Shavasana, 10 minutes of guided rest, useful in the evening if sleep is poor.

Yoga after meals

Most poses are best done 2 to 3 hours after eating. Two habits fit right after a meal:

• Sit in Vajrasana for 5 to 10 minutes instead of lying down.
• Walk slowly for 10 to 15 minutes.

Avoid forward bends, twists, Kapalbhati and strong practice on a full stomach.

Myths to ignore

• "This pose massages the pancreas." You will often read that twists or backbends squeeze the pancreas and make it release insulin. There is no good evidence for this. The benefits come from activity, lower stress and weight, not from pressing on an organ.
• "Yoga can reverse diabetes, so you can stop medicine." Some people with type 2 diabetes do reach normal sugar levels through big changes in weight, food and activity, but only with their doctor's supervision. Yoga alone does not do this, and stopping medicine on your own is dangerous.
• "More Kapalbhati means lower sugar." Long sessions of forceful breathing are not proven to lower sugar and can be risky with high blood pressure or heart disease.
• "Any one pose is the best for diabetes." What matters is a regular, varied practice you can keep up, not a single magic asana.

How to know it is working

• Practise for at least 3 months before judging. HbA1c reflects about 3 months of sugar levels.
• Keep a simple log of your fasting and after-meal readings if your doctor asks you to monitor at home.
• Note other changes too: sleep, energy, waist size, stress and how far you can walk.
• Share the log at your next check-up so your doctor can adjust your treatment if needed.
