Safety

Shilajit before and after surgery

There is no research on shilajit and surgery. Because its interactions with anaesthetics, blood clotting and blood sugar haven’t been studied, the safest approach is to tell your surgical team you take it and follow their advice, which often means stopping herbal and dietary supplements for a period before an operation. After surgery, wait until your team says it is fine to restart, especially if you have new medicines.

Key facts
  • No research on shilajit and surgery.
  • Tell your surgical and anaesthetic team you take it.
  • Teams often ask patients to stop supplements before surgery.
  • Restart only when your team agrees.

Why surgery is a special case

Surgery and anaesthesia involve medicines, changes in blood pressure and blood sugar, and blood clotting, all of which supplements could, in principle, affect. Shilajit hasn’t been studied in any of these areas. Animal research suggesting effects on blood sugar is a theoretical reason for caution around the fasting and stress of surgery.[1] Interactions with medicines are also unstudied; see medication interactions.

Tell your surgical team

Pre-operative assessment usually asks about medicines and supplements. Mention shilajit by name, how much you take and for how long, and bring the product or a photo of the label. Many people forget to mention supplements because they don’t think of them as medicines; your team needs the full picture to plan anaesthesia and recovery safely.

Stopping before surgery

Surgical and anaesthetic teams commonly ask patients to stop herbal and dietary supplements for a period before an operation, often around a week or two, though the exact advice varies. Follow the specific instructions you are given. If you haven’t been told, ask at your pre-operative assessment rather than guessing.

Emergency surgery

In an emergency there may be no time to stop. Tell the team, or ask someone with you to tell them, that you take shilajit. Keeping a list of your medicines and supplements in your phone or wallet makes this easier.

After surgery

Recovery often involves new medicines, such as painkillers, antibiotics or blood thinners to prevent clots. Check with your team or pharmacist before restarting shilajit, and wait until you are eating normally and your wound is healing well. There is no evidence that shilajit speeds recovery or healing, so there is no reason to rush back to it.

Dental procedures

For dental work involving anaesthesia or extractions, mention supplements to your dentist too, particularly if you also take blood thinners.

Why anaesthetists ask about supplements

Anaesthesia involves carefully balanced medicines and close control of blood pressure, heart rate and breathing. Some supplements are known to affect bleeding, blood sugar or how anaesthetic drugs work. For shilajit, effects are simply unknown, which is exactly why the team wants to know. Telling them is about giving them the full picture, not about getting into trouble.

Questions to ask at pre-operative assessment

  1. When should I stop shilajit before surgery?
  2. Should I stop any other supplements?
  3. When can I restart after surgery?
  4. Will any new medicines affect that?

Supporting recovery

After surgery, rest, gradual activity, good nutrition, hydration and following wound-care advice support recovery. If you want to support healing through diet, a balanced diet with enough protein is the established approach, and your team can advise if supplements such as vitamins are appropriate.

Other procedures

The same principles apply to smaller procedures under sedation or local anaesthetic, such as endoscopy or minor skin surgery. Mention shilajit at booking and follow the instructions you are given.

After you restart

When you restart, go back to your usual label serving rather than catching up on missed days, and watch for any new symptoms, particularly while you are still taking post-operative medicines.

During a hospital stay

Don’t take your own supplements in hospital unless the ward team agrees. Hospital teams need to know everything you take, so they can manage your medicines safely while you are in their care.

Bring a written list

Bring a written list of your medicines and supplements, including shilajit and your usual serving, to your pre-operative assessment and on the day of surgery.

Putting it into practice

As soon as surgery is booked, add shilajit to your medicines list. Confirm the stopping date at your pre-operative assessment, stop as advised, and bring your list on the day. After surgery, check with your team or pharmacist before restarting, especially if you have been given new medicines such as blood thinners or antibiotics.

The bottom line

Shilajit hasn’t been studied around surgery, so treat it like any other supplement: tell your team, stop when advised, and restart only when they agree. There is no benefit to continuing it through an operation, and caution costs nothing.

Frequently asked questions

Should I stop shilajit before surgery?

Tell your surgical team and follow their advice. Teams commonly ask patients to stop supplements for a period before surgery.

How long before surgery should I stop shilajit?

Follow your team’s instructions; common advice for supplements is around a week or two, but it varies.

Can shilajit affect anaesthesia?

Not studied. That is why your anaesthetic team needs to know you take it.

Does shilajit affect bleeding?

Not studied. Mention it, especially if you take blood thinners.

When can I restart shilajit after surgery?

When your team agrees, typically once you are eating normally and any new medicines have been checked.

Does shilajit help recovery after surgery?

There is no evidence that it speeds recovery or healing.

What if I forgot to stop shilajit?

Tell the team before the operation; they will decide whether to proceed.

Does this apply to dental treatment?

Mention supplements to your dentist, particularly for extractions or if you take blood thinners.
