Ask the GP: Probiotics could clear up your bad case of wind

Making changes to your gut microbiome may take months, but there's reason to be optimistic.
Dr Martin Scurr

Q: RECENTLY I had a colonoscopy. Despite sedation, it was the most painful procedure I've ever endured. Worse, it's left me with dreadful wind. I'm an otherwise fit and healthy 80-year-old. My GP has suggested probiotics.

A: I AM sorry you suffered such extreme discomfort during and after the colonoscopy. The good news is that there was no sign of disease, such as cancer.

But as for your current problem, I agree with your GP: the highly offensive gas you describe in your longer letter is because of a disturbance to the microbiome, the vast array of tiny organisms that live in our gut.

Somehow, the balance of these organisms has become altered so those that create malodorous gas, such as hydrogen sulphide and methane, are more prevalent.

Taking probiotics, as your GP has suggested, is a sensible way to tackle this. Look for products with a large number of bacteria per dose (at least ten million). In addition, try to eat fermented foods daily, as this will add more 'good' bacteria to your microbiome. I recommend live yoghurt and kefir (fermented milk that's now widely available in supermarkets).

Sauerkraut is another option, although this needs to be fresh from the fridge, rather than from a jar, as pasteurisation can kill off the very bugs you want.

And think about adding prebiotic foods to your diet. These contain the fibre that 'feeds' the friendly bacteria you want to encourage.

Good sources of prebiotics include Jerusalem artichokes, leeks, garlic, onions, asparagus, bananas, oats and apples. But, as always, more doesn't necessarily mean better: introduce these foods slowly so you don't aggravate the current windiness.

Making changes to your microbiome may take months, but there's every reason for optimism.

Meningiomas are the most common type of brain tumour and don't usually cause symptoms.

Q: THREE MONTHS months ago I had a giddy spell that put me in hospital. Later I was told a CT scan had shown a calcified meningioma [brain tumour], which came as rather a shock. My GP has told me it's 8mm, and is in the right frontal area of my brain.

A: MENINGIOMAS ARE the most common type of brain tumour and are usually discovered only when the brain is scanned for other reasons. I suspect in your case this was to rule out a stroke.

Let me first reassure you that the word 'tumour' means lump, not cancer. Meningiomas are benign, slow-growing lumps in the meninges, the membrane that covers the brain. One study suggests they occur in about 1 per cent of the population, mostly in those aged 65 and over.

Meningiomas don't usually cause symptoms - dizziness only occurs with a meningioma in the rear lower part of the brain. For those in the frontal lobes, as yours is (and particularly one as small as yours), I wouldn't expect any symptoms.

'Calcified' means your meningioma has hardened and is unlikely to grow much, if at all.

I suggest that it is for those reasons your hospital doctors took no further action, though in my opinion the professional approach would have been to call you in and explain the findings. I'd suggest it's advisable to have another scan after one year, with further scans depending upon whether there's been any increase in size.

In one study involving 400 patients, just 11 per cent of meningiomas grew larger.

Treatment is only necessary when a meningioma becomes so large that it causes a neurological impairment, and then radiotherapy or surgery is advised.

In my nearly 40 years as a GP, I've never seen a case of meningioma becoming malignant.

In conclusion, the best course is watchful waiting, with a follow-up scan in due course.
