Notice a bulge in your abdomen or groin that comes and goes? Don’t ignore it.

One of the most common signs of a hernia is a bulge that becomes more noticeable when you stand, cough, lift something heavy, or strain, then disappears when you lie down or relax.

Hernias aren’t always painful. Some patients experience discomfort or pressure, while others have no symptoms at all.

Just because a bulge disappears doesn’t mean the underlying problem has gone away.

If you’ve noticed an unexplained bulge, it’s important to have it evaluated by a surgeon. Not every hernia requires immediate surgery, but understanding what’s causing it can help prevent complications down the road.

Seek emergency care if a bulge becomes severely painful, cannot be pushed back in, or is accompanied by vomiting or skin discoloration.

Transformations like this are why I do what I do. Weight loss surgery isn’t simply about changing how someone looks. It’s about helping patients take control of their health and work toward a better quality of life.

Bariatric surgery can provide a powerful tool for patients struggling with obesity, helping support significant, long-term weight loss while improving conditions like type 2 diabetes, high blood pressure, and sleep apnea.

The physical changes may be what you notice first, but the potential health benefits are what make these transformations so meaningful.

If you’ve struggled to achieve lasting weight loss through diet and exercise alone, bariatric surgery may be an option worth exploring.

Gallstones are one of the most common gallbladder conditions, and cholesterol plays a major role in how they form.

Your gallbladder stores bile, a digestive fluid that helps your body break down fats. When bile contains more cholesterol than it can dissolve, that cholesterol can begin forming crystals. Over time, those crystals can grow into gallstones.

But cholesterol isn’t the only factor. Genetics, obesity, rapid weight loss, and certain medical conditions can also increase your risk of developing gallstones.

Many gallstones cause no symptoms, but if a stone blocks a bile duct, it can lead to significant abdominal pain, nausea, and other complications.

Understanding what causes gallstones is an important first step in recognizing when gallbladder problems may require medical attention.

Ever notice your heartburn gets worse the moment you lie down at night?

There’s a reason acid reflux tends to flare up after dinner, especially when you head straight to bed.

When you’re standing or sitting upright, gravity helps keep stomach acid where it belongs. But when you lie down, that natural assistance disappears, making it easier for acid to travel back into your esophagus.

Add a large meal, increased stomach pressure, or a weakened lower esophageal sphincter, and you may experience that familiar burning sensation in your chest or sour taste in the back of your throat.

If you’re experiencing frequent nighttime acid reflux or GERD symptoms, try avoiding large meals within 2–3 hours of bedtime and consider getting evaluated if symptoms persist.

Chronic acid reflux shouldn’t be ignored, especially when it’s regularly disrupting your sleep.

A transformation that goes far beyond the number on the scale.

For many patients, weight loss surgery is the beginning of a completely new chapter. From improved mobility and energy levels to a reduced risk of obesity-related health conditions, the benefits can extend into nearly every aspect of daily life.

This patient’s before and after is a great reminder of what’s possible with the right medical support, long-term lifestyle changes, and a commitment to better health.

Considering bariatric surgery? Schedule a consultation with Dr. Michael Feiz to learn more about your options.

Struggling with weight gain even though you feel like you’re doing everything right?

Your daily habits may be playing a bigger role than you realize. From how much you move throughout the day to your eating patterns, hydration, and protein intake, several factors can influence your ability to lose weight and maintain it.

But not every habit affects everyone the same way. Snacking, eating late at night, or skipping intermittent fasting won’t automatically cause weight gain. Your overall calorie intake, activity level, sleep, and metabolic health all play a role.

Sustainable weight loss isn’t about following every diet trend. It’s about understanding which habits actually make a difference for your body.

Bariatric surgery is about so much more than the number on the scale.

One of the biggest misconceptions about weight loss surgery is that you’ll never be able to enjoy food again. The reality? Most patients can return to enjoying a variety of foods, just in smaller portions and with healthier habits.

And while the physical transformation gets the most attention, the real benefits go far beyond appearance. Bariatric surgery can improve or even resolve obesity-related conditions like type 2 diabetes, high blood pressure, and sleep apnea, while helping patients achieve better long-term health.

The goal isn’t just weight loss. It’s a longer, healthier life.

If you’ve been thinking about weight loss surgery but keep telling yourself, “maybe I can do it on my own,” it may be time to at least have the conversation.

Transformations like this don’t happen overnight, and surgery isn’t a shortcut. It’s a tool that can help you make a lasting change when other approaches haven’t given you the results you’re looking for.

You don’t have to decide today that you’re having surgery. Start with a consultation and find out what your options actually are.

Bariatric surgery is the “easy way out.” Myth.

Making the decision to have weight loss surgery is a major commitment, and surgery is only one part of the process. Long-term success also requires changes to nutrition, physical activity, sleep and your overall lifestyle.

There’s a lot of outdated information surrounding bariatric surgery. Let’s fact check it.
