For a small, inessential body part, the gallbladder can cause a lot of pain. Roughly the shape and size of a pear, the organ sits in the right side of your abdomen. Its job is storing bile, a liquid produced by the liver that helps you digest the fats in your diet. The gallbladder releases the liquid as needed into the small intestine. (Here are more body parts you never knew you had.)

What causes gallstones?

When bile’s delicate chemical balance gets thrown off—we don’t fully know how or why—its components can crystallize. Over years, these crystals can combine to form gallstones (medical term: cholelithiasis), which can be as tiny as grains of sand or as large as golf balls. In at least 75 per cent of cases, gallstones don’t cause symptoms or complications and therefore don’t require treatment.

What do gallstones feel like?

However, should a stone temporarily block one of the bile ducts leading in and out of the gallbladder, the result is a sudden, short-lived bout of gripping or gnawing pain in the abdomen, rib cage area or shoulder. This won’t cause lasting damage, but you might like to visit a doctor to confirm that it is indeed gallstones and not another problem, such as an ulcer. (Here are more ulcer symptoms to watch out for.)

Longer-term or permanent duct blockage can lead to serious complications, like infections and inflammation. Therefore, you should see a doctor immediately if you experience symptoms that include jaundice, fever, chills or incessant pain.

Who is most at risk for gallstones?

Gallstones have a greater chance of developing in women, adults over the age of 40 and people with a family history of the condition. Beyond that, the major correctable risk factor is obesity, says Dr. Stephen Ryder, medical adviser to the British Liver Trust. But Ryder cautions against shedding weight quickly: “Rapid weight loss or gain can cause stones to form and can trigger symptoms, so controlled weight loss is best.”

How are gallstones treated?

If you already suffer from symptomatic gallstones and the attacks are mild, you could manage their effects with painkillers; a low-fat diet may also make a modest difference. If your symptoms are severe and frequent, the only effective treatment is the sur­gical removal of the gallbladder.

You can live without the organ: your liver will still produce bile, which will drip directly into the small intestine rather than collecting in the gallbladder first. Post-­surgery, approximately one in 10 patients experience occasional diarrhea as their digestive systems adapt to the continuous release of bile. The diarrhea might last anywhere from weeks to years, but medications called bile acid binders can help control this unpleasant side effect. For most people, though, the difference between having a gallbladder and not having one is unnoticeable.

Brianne Miller At Nada - zero-waste grocery store
Brianne Miller at Nada

In the 2010s, 34-year-old Brianne Miller travelled around the world as a marine biologist. No matter how remote the location, she made the same alarming discovery: copious amounts of plastic littering the water and threatening marine life. Miller knew she needed to do something. 

Canadians throw out three million tons of plastic waste each year. Groups like A Greener Future, which organize litter clean-ups across Canada, estimate that 33 per cent of what they pick up comes from food packaging. Approximately one third of all food produced worldwide goes to waste, too, according to a United Nations study. (If food waste were a country, it would be the third-largest producer of greenhouse gases.) Miller, determined to fix the problem at the source, envisioned a shop that went further than banning plastic bags—a place that eschewed both wasteful packaging and the bad habit of wasting food itself. 

In 2015, she cold-called a Vancouver Patagonia store and, explaining how her mission mirrored that brand’s emphasis on sustainability, convinced its managers to host her first pop-up. Her stock consisted of about 10 jars of dried mangoes, locally made chocolate, nuts and some pasta. She sold out in one afternoon—and knew she was onto something. 

In June 2018, after another year and a half of successful pop-ups, Miller opened one of the first zero-waste grocery stores in Canada. She named it Nada, and ensured everything was designed to make the zero-waste shopping experience easy. You can bring your own containers, though it’s not necessary: right by the front door are well-organized bins of “upcycled” sanitized glass or plastic containers, free for the taking. 

Nada sells the food items you’d expect—dried pasta, whole grains, spices and baking ingredients—and hundreds you wouldn’t, like jam, frozen fruit, perogies and kimchee, all 100 per cent package-free. As items approach their expiry date, the in-store café uses them to make baked goods, soups and more. To offer this variety, Miller buys from some 115 small, local companies. The suppliers must have a social or environmental mission, and just as importantly, they must work to reduce waste in their own supply chain. 

Miller is clear that the store doesn’t try to compete on price. For example, popcorn kernels at a generic store may cost 70 cents per 100 grams; at Nada, a customer might pay $1 per 100 grams, knowing that the kernels are organic and non-GMO. Even so, zero-waste shopping can still come with savings. Take products that typically come packaged in bulky containers, like spaghetti sauce; a large part of the traditional cost would be in that glass jar. 

The early days of the pandemic were tough on the business. Because bulk food sales were restricted, Nada closed its doors to the public for 18 months. Miller pivoted to online ordering and delivery, though in a very Nada way. Carbon neutral deliveries are made by e-bike and, as of February, via a fleet of electric vehicles. Everything from olive oil to fresh eggs (and you can purchase just one, if you’d like) comes delivered in upcycled containers, which are collected (and reused again, of course) with the next round of deliveries. 

Those containers do so much more than just reduce waste. They get people thinking big, just as Miller had hoped they would. “They’re tagged with Nada stickers, so you can see how many times the container has been used,” she says, and then smiles. “If you open someone’s pantry and see all of these Nada-branded quirky packages, it’s bound to start a conversation.”
