Dear Doctor: My daughter had her gall bladder removed, and two months later she’s still suffering from watery diarrhea. She even had to be hospitalized to restore her fluids. What does your gall bladder do? Are there lifestyle or dietary adjustments that could help?

Dear Reader: The gall bladder is a small, pouchlike organ that is located in the upper-right quadrant of the abdomen, just below the liver and next to the pancreas. When distended, the gall bladder is about the size and shape of a small pear. Its job is to store bile, a complex digestive fluid that is made and released by the liver.

One of the roles of bile is to break down fatty foods into smaller components, including fatty acids. This is so that fats, along with fat-soluble vitamins, can be readily absorbed in the small intestine during digestion. Bile also aids in the elimination of certain waste products. Each time you eat fatty foods, your gall bladder contracts and squeezes a bit of bile into the small intestine.

Surgical removal of a gall bladder is known as cholecystectomy. These days, it’s most often a noninvasive laparoscopic procedure. The surgery can become necessary due to the presence of gallstones, which are hardened deposits that can form within the bladder. Gallstones may leave the bladder via the bile duct, a process that can be extremely painful. However, sometimes due to their size, quantity or position within the gall bladder, gallstones aren’t able to exit. They may block the bile duct, which can cause pain and lead to infection. Signs of gall bladder problems include abdominal pain and tenderness, excessive gas, chronic indigestion, fever, chills, nausea and jaundice.

The diarrhea that your daughter is experiencing is believed to occur in 10% to 20% of people who have had their gall bladders removed. The reason for it isn’t really clear. One theory is that, without the gall bladder to store bile, the increase in bile and bile acids within the intestines creates an environment that leads both to watery stools and increased muscular contractions. Basically, the excess bile and bile acids act as a laxative.

In most cases, this post-surgical diarrhea will resolve in the days and weeks following gall bladder surgery. In the short term, anti-diarrheal medications such as Imodium A-D may be used to get bowel movements under control.

Some people with this type of diarrhea find it helpful to eliminate caffeine, sweets or dairy products from the diet. If your daughter’s condition persists, her doctors may consider prescribing cholestyramine, a cholesterol medication that uses nondigestible resins to bind up the bile acids within the intestines. Due to the binding properties of cholestyramine, it’s important after a dose to wait four to six hours before taking other medications or supplements. Following a low-fat diet may help boost cholestyramine’s efficacy.

CVI Not Life-Threatening, Can Cause Complications

Dear Doctor: I was recently diagnosed with chronic venous insufficiency in both legs. What is it, and why does it happen? What does it mean for my health?

Dear Reader: One of the tradeoffs of the evolution of upright posture in humans is that at some point, the various fluids that circulate throughout our bodies face an uphill climb. This is particularly true of our blood, which gets pumped from a location high up in the body. Not only does it need to reach all of our tissues, but it has to complete a timely round trip back to the heart.

A branching network of arteries carry oxygenated, nutrient-rich blood away from the pumping chambers of the heart and out to the tissues via the capillaries. A similar network of veins return oxygen-poor blood and waste products back to the heart.

When you have chronic venous insufficiency, or CVI, it means that the deeper veins in your legs aren’t working efficiently to return the blood to the heart. This happens when the walls of the veins become weakened, and when the tiny one-way valves within the veins no longer function properly. These valves are an ingenious solution to the gravity fighting against the blood moving up from your legs back to the heart.

Working in concert with our muscles and with the smooth and elastic vein walls, these valves use a pair of opposing flaps to prevent the rising blood from ebbing backward between heartbeats. With CVI, the blood fails to make a consistent upward climb and pools in the veins. Blood pressure within the veins rises, which can damage both the veins and the valves.

Risk factors for CVI include age, family history, prolonged inactivity, pregnancy, obesity and being quite tall. CVI may also occur in people who have experienced deep vein thrombosis, which is a blood clot in the deep veins of the leg. Symptoms include swelling in the lower leg and ankle -- particularly after prolonged standing -- as well as aching, throbbing or tiredness in the legs. Skin on the legs and feet may itch, flake or appear leathery, and new varicose veins may emerge. The condition becomes more common after age 50, and is seen more often in women than in men.

Chronic venous insufficiency is not life-threatening; if ignored, however, it can lead to serious complications. These include leg ulcers, pulmonary embolism, deep vein thrombosis and secondary lymphedema, which is swelling in the tissues due to damage to the lymphatic system.

Depending on the severity of your particular condition -- there are varying degrees of CVI -- your doctor will outline strategies for you to follow. These can include being advised to lose weight, wear compression stockings, exercise regularly, elevate the legs, avoid prolonged standing and maintain skin care. Some patients benefit from nonsurgical treatments that use injected solutions or laser therapy to collapse certain smaller vessels.

It’s important for your health that you follow your doctors’ recommendations and make managing CVI part of your daily routine.

Diet and Exercise Can Help With Arthritis

Dear Doctor: I am 67 years old, with arthritis in my hands and feet. My daughter recently had a fall, and X-rays showed signs of arthritis in her foot. She’s only 34. What are the most important things she can do to keep it from progressing, or at least slow it down?

Dear Reader: When we talk about arthritis, we’re referring to a range of conditions that result in pain, stiffness and swelling that affects the joints, most often in the hands, feet, hips and knees. Although rare, the inflammation from certain types of arthritis can affect other parts of the body, such as the kidneys, heart, eyes and lungs. Arthritis occurs in people of both sexes, and of all ages, races and body types. It is estimated that up to one-fourth of Americans are living with some type of arthritis, which makes it one of the leading causes of disability in the U.S.

The two most common types of arthritis are osteoarthritis and rheumatoid arthritis. The former is caused by wear and tear of the joints. The latter is an autoimmune disease in which the person’s own immune system attacks and damages the connective tissues. Both result in similar symptoms, which include stiffness in the morning and after inactivity, pain while walking, localized joint pain and swelling, tenderness or warmth within the joints.

There are several things your daughter can do to manage the progression of arthritis. (And these can benefit you, as well.) One is to maintain a healthy weight, which lessens the daily toll on the joints in the feet, hips and knees. A healthful diet, with an emphasis on lean proteins and a wide variety of fresh fruits and vegetables, is important. So is minimizing foods known to kick up inflammation, which includes refined starches, added sugars, red meat and saturated fats and trans-fats.

It may seem counterintuitive, but staying active lessens arthritis pain, keeps joints moving and increases range of motion. Go for joint-friendly exercises that are enjoyable enough to do regularly. These include low-impact options such as walking, cycling, tai chi, yoga, Pilates, swimming and water aerobics. Strength training, which helps to build up the muscles that support your joints, can also be very helpful. However, it’s best for this to be done under supervision, at least in the beginning.

As when adding any new exercise to your daily routine, it’s a good idea to first check in with your health care provider. Which leads us to a final bit of advice: If your budget and health insurance allow, we think it would be wise for your daughter to have at least one visit with a rheumatologist. They can assess her condition, provide her with a baseline from which to evaluate the progression of her arthritis and help educate her on what to expect in the future. If she’s experiencing pain, they can help her explore a range of options to deal with it. The more she knows about arthritis in general -- and her condition in particular -- the more active she can be in participating in her own care.
