Wholehearted Healthcare

Richard Knox isn’t afraid to trust his gut. When the Hiram resident began experiencing abnormal bowel habits, he instantly knew something was off. What happened next involved advocating for his health, finding the right team of specialists to meet his needs and understanding the lifesaving role of a colonoscopy in catching colon cancer early.

Becoming an advocate

Born and raised in Smyrna, Richard spent a fulfilling career with AT&T and called many different cities “home” before his retirement in 1998. He moved back to Georgia and settled in a house by the golf course at Creekside Golf & Country Club.

Richard enjoyed an active lifestyle and managed to stay healthy; in fact, the only time he could remember staying in the hospital was in 1952 when he had his tonsils removed. However, his maternal grandfather died of colon cancer at age 65, so Richard wanted to stay proactive about his colon health, knowing his family history. He had his first routine colonoscopy in his 50s, per his physician’s recommendations—“just trying to be preventative,” he said. (Updated guidelines from the American Cancer Society now recommend that individuals at average risk for colorectal cancer start screening at age 45.)

His third colonoscopy, in 2018, showed no major cause for concern—though a blood test at the time revealed anemia. A few years later, Richard noticed some changes in his bowel habits, including persistent constipation, that made him question his health. He consulted a gastroenterologist, who instructed him to stop taking Tylenol at night to help alleviate his symptoms.

But everything wasn’t fine. “It went on for several months. It wasn’t changing, and it wasn’t getting any better,” said Richard. That’s when he knew it was time to seek a fresh perspective.

Right care, right time

Richard turned to his Wellstar primary care physician, Dr. Roderick Rhyant, whom he and his wife had seen regularly since moving to Hiram. Dr. Rhyant helped coordinate care by referring Richard to a Wellstar specialist, board-certified gastroenterologist Dr. Benjamin Renelus.

During his first appointment with Dr. Renelus, Richard shared the results of his previous colonoscopies and recounted the recent gastrointestinal issues he’d been having. He described Dr. Renelus as someone who “lights up the whole atmosphere” and made him feel at ease discussing what can be a sensitive or difficult topic for many people.

“Richard was by and large very healthy for his age,” Dr. Renelus explained. But something wasn’t quite adding up: “What I saw in his labs was that his hemoglobin started to trend down, [indicating] there may be a GI bleed going on… but he’s not complaining of any abdominal pain. I thought, ‘This may be a tumor.’”

Like Richard, Dr. Renelus trusted his instincts—and when he didn’t feel confident with his patient’s prior colonoscopy report, he recommended a diagnostic colonoscopy. This screening test would allow him to directly examine the inside of the colon and rectum, and take a biopsy of any abnormal colon tissue.

“[Dr. Renelus] just looked at me and said, ‘You know what I’m going to say,’” Richard recalled with a laugh. “And I said, ‘That’s fine, doc. Whatever we’ve got to do. I’ve got to figure out what’s causing this.”

Knowing Richard was fit and healthy enough to undergo the procedure, Dr. Renelus scheduled the colonoscopy at the Outpatient Surgery Center at Wellstar Vinings Health Park. As it turned out, those gut feelings were right: The screening detected obstructive colon cancer.

Collaborative approach

Dr. Renelus shared the diagnosis with Richard, explaining that he had a malignant tumor originating from his colon.

“Breaking bad news, unfortunately, is something that’s not foreign to us as gastroenterologists,” he said. “But the good news is we have all the people in place at Wellstar.”

The physician promptly referred Richard to two of his Wellstar colleagues: Colorectal Surgeon Dr. Anushka Arumugasaamy, who would remove the tumor; and Hematologist/Oncologist Dr. William Forehand, who would oversee Richard’s colon cancer treatment and management.

“He was able to be seen so quickly,” Dr. Renelus said. “And I saw him in the office in between everything that was going on. He was always in good spirits. He trusted the process; he trusted me. There has to be trust on both sides. He did everything that we laid out for him.”

Richard first met with Dr. Arumugasaamy to assess the tumor. She ordered several imaging tests, including a lower abdominal CT scan and an MRI, to help stage Richard’s colon cancer and determine the most effective surgical approach. She then performed surgery to remove the tumor at Wellstar Cobb Medical Center.

The surgery was a success, and Richard experienced minimal pain afterward. Several months later, he saw Dr. Forehand to discuss next steps. Thankfully, Richard’s cancer levels looked good, so Dr. Forehand said they would continue to monitor for any signs of cancer recurrence.

When he returned to Dr. Forehand’s office six months later, the CT scan was “perfectly clear,” said Richard. As a final step, Dr. Renelus performed a post-surgery colonoscopy, where he removed one polyp and confirmed all cancer had been removed.

Richard will continue to see Dr. Forehand annually to ensure he remains cancer-free. “People who develop colon cancer have a 3% risk of developing another cancer within 10 years, so that’s a sizable number considering what they’ve already been through,” explained Dr. Renelus. “Ongoing surveillance is very important.”

Throughout his colon cancer treatment, Richard said he was treated with respect and compassion by every member of his Wellstar care team.

He especially appreciated Dr. Renelus’ expertise and guidance at every step. “He was great,” Richard shared. “The colonoscopy experience with him and the folks at Wellstar Vinings Health Park was fantastic.”

Screening saves lives

As colon cancer continues to rise—it is now the third most common cancer worldwide and ranks second in cancer-related death—regular screenings have become even more important.

“Colonoscopy is unique in the sense that it can prevent colon cancer by removing cancerous polyps,” explained Dr. Renelus. “And if you are diagnosed with colon cancer and we’re able to catch it at an earlier stage, your chance of survival exponentially increases.”

“I want people to trust themselves and if something feels off, go to the doctor,” he continued. “The reality is early detection is best.”

It’s also essential that patients feel comfortable bringing up any concerns with their healthcare providers, as open communication can make a big difference in treatment outcomes. In Richard’s case, Dr. Renelus said that “had he not trusted his gut or not mentioned some of these cue words with me, I don’t know if the colonoscopy would have even been explored with someone like him.”

In sharing his story, Richard hopes he can encourage others to let go of their fears and go get screened.

“If you start noticing something is different—[that] a normal process of your body changes—you need to understand why,” he shared. “That’s what happened to me, and I was fortunate to get my appointment with Dr. Renelus.”

“And if it is colon cancer, don’t give up,” he continued. “It’s very treatable when caught early. The doctors and the facilities are well equipped to do it. So get it taken care of before it gets worse.”

Pregnancy is a time of excitement and change. But it also puts added strain on the heart. In fact, cardiovascular conditions are one of the leading causes of maternal complications worldwide. Some women can develop heart conditions during pregnancy that can lead to serious complications if not recognized early. Knowing the risks and being proactive about your heart health can help prevent a life-threatening problem.

Here’s what every expectant mom should know about heart health during pregnancy.

1. High blood pressure can be silent—and dangerous.

Some women develop high blood pressure during pregnancy, even if they’ve never had it before. High blood pressure can lead to preeclampsia. It’s a condition that can cause organ damage and, in severe cases, seizures. When high blood pressure isn’t treated, it can increase the risk of stroke or heart failure. Checking your blood pressure regularly can help catch problems early.

What to do about high blood pressure

If you have a history of high blood pressure, heart disease or a family history of cardiovascular issues, tell your care team. Preconception counseling is essential if you have a known heart condition. Your physician may recommend that you monitor your blood pressure at home and report any sudden swelling, headaches or vision changes immediately.

2. Heart failure can happen—even in healthy moms.

A rare but serious condition called peripartum cardiomyopathy (PPCM) weakens the heart, usually in the last month of pregnancy or the months following delivery. If you have shortness of breath, swelling or often feel extremely tired, don’t ignore those signs.

What to do if you have shortness of breath or a racing heart

Talk to your provider immediately if everyday activities leave you exhausted or struggling to breathe. Other concerning symptoms include persistent coughing, swelling in your legs or feet and dizziness. Don’t ignore symptoms like chest pain, shortness of breath, severe fatigue or a racing heartbeat. These could signal a serious heart problem—seek help right away.

3. Pre-existing heart conditions and hypertensive disorders require extra care.

If you’ve ever had heart disease, a heart defect or high blood pressure—including hypertension or hypertensive disorders—pregnancy can increase your risks. Even women without symptoms before pregnancy may need extra monitoring.

What to do if you have a pre-existing heart condition

Talk with your provider early about a care plan. High-risk pregnancies may require specialist support, like a maternal-fetal medicine physician or cardiologist. If you’ve been diagnosed with a heart condition before pregnancy, ask your provider how it may affect labor and delivery. If something doesn’t feel right, speak up. You know your body best, and your concerns deserve attention.

4. Blood clots are more common during pregnancy.

Pregnancy increases the risk of thromboembolism, a serious condition where blood clots can travel to the lungs and cause a pulmonary embolism. The risk is even higher for women with a history of clotting disorders, obesity or limited mobility.

What to do to prevent blood clots

To reduce your risk of blood clots, stay active, stay hydrated and watch for warning signs like leg swelling, redness or pain. If you notice these, call your provider right away. If you’re on bed rest, ask your provider about ways to improve circulation. Learn the signs of deep vein thrombosis and pulmonary embolism.

5. A racing heartbeat may be abnormal.

You can expect some changes in heart rhythm during pregnancy, but arrhythmias (irregular heartbeats) can be a sign of something more serious. Hormone changes, increased blood volume and underlying conditions like thyroid disorders can all contribute to an irregular heartbeat.

What to do about a racing heart

If your heart races often, feels like it’s skipping beats or you feel dizzy or faint, let your provider know immediately. Keep track of when these symptoms happen and whether they occur at specific times, such as during physical activities or when your stress levels are high.

6. Postpartum recovery still puts stress on the heart.

The risk of heart complications doesn’t end at delivery. Many serious conditions, including heart failure or high blood pressure, can develop in the weeks or months after childbirth. Postpartum heart issues can be life-threatening if you don’t address them.

What to do during the postpartum period

Keep all postpartum checkups, even if you feel fine. Watch for new symptoms like chest pain, shortness of breath or extreme fatigue. If you had high blood pressure during pregnancy, continue monitoring it after delivery. Be aware that cardiovascular complications can develop up to a year postpartum, and follow-up care is so important for your long-term health.

7. Your hospital choice matters

For women at high risk, delivering in a hospital with access to specialized prenatal tests, genetic testing like amniocentesis, fetal evaluations and emergency cardiac care can make all the difference. Not all hospitals have the same level of maternal heart care, so it’s important to plan ahead. Choose a hospital that is equipped to handle pregnancy-related cardiac emergencies.

What to do about your hospital choice

If you are high-risk, consider hospitals with advanced cardiac care and those that have expertise in pregnancy-related heart conditions. Talk to your care team well in advance about your birth plan, especially if you have a heart condition. If possible, tour the hospital beforehand and ask about its capabilities in managing pregnancy-related heart complications.

8. Mental health and stress impact heart health.

Anxiety and stress can affect your heart. If you’re feeling overwhelmed, talk to someone. Your mental health is just as important as your physical health. Depression, anxiety and even post-traumatic stress disorder are common in pregnancy and postpartum, and they can impact heart health.

What to do to keep your mental health in check

Access mental health resources and practice stress management techniques to help you manage your mental health. Simple practices like deep breathing, mindfulness and connecting with loved ones can help lower stress levels. Remember, you are empowered to take control of your health—talk with your provider or a support person and get the help you need.

Take Action for a Healthier Pregnancy.

Eat well, stay active and avoid smoking or alcohol. These efforts can protect your heart and your baby’s health. Small, consistent changes—like reducing salt intake or walking daily—can make a difference.

Regular prenatal visits are just as important. Remember, knowledge is power. Stay informed, speak up when something feels off and choose a hospital that meets your needs. These simple steps can help you take control of your heart health and reduce the risk for you and your baby.

Wellstar Cobb Medical Center is no stranger to using robotics in surgery yet a new system has catapulted its robotic capabilities to the next level.

Wellstar Cobb is the first hospital in the health system to offer a first-of-its-kind surgical technology through the new Da Vinci 5 robot (DV5), with surgeons Dr. Julie Chang and Dr. Stephen Odom performing the hospital’s inaugural procedures using the DV5 for gynecologic and general surgery.

The DV5 robot allows physicians to sense how much push-or-pull force they apply during surgeries, giving them greater control and data as they delicately maneuver the tips of the instrument. Wellstar Cobb is among the first hospitals in the metro Atlanta area with this innovative technology.

“The ability to sense hard and soft tissue during robotic surgeries is a game changer,” said Dr. Chang, a specialist in obstetrics and gynecology and the first surgeon to use the new DV5 robot at Wellstar Cobb. “Surgeries will be even more precise and efficient with this tool, which will further reduce post-operative pain and make recovery time faster.”

Surgeons can apply up to 43% less force on tissue by relying on the robot’s Force Feedback technology, according to preclinical data from Intuitive, the maker of the DV5 system. When using DV5, surgeons also benefit from improved dexterity and ergonomics, better 3D images and a wider range of motion compared to prior models.

This increase in precision and flexibility will help patients experience less blood loss and scarring, have lower risks of complications and spend less time in the hospital.

“We are committed to providing the highest standard of care—not only by building strong teams, but also by embracing cutting-edge technology,” said Eliese Bernard, president of Wellstar Cobb. “We are thrilled to offer this latest advancement to our patients and be among the first hospitals in the state to do so.”

The new system will primarily benefit general surgery, urology and gynecology patients. DV5 will assist with procedures ranging from repairing a hernia to more complex surgeries.

Wellstar Cobb has performed over 10,000 robotic surgeries, with 1,500 of those procedures occurring last year alone. With the help of various Da Vinci models, the hospital’s 30 robotic surgeons apply their expertise to general surgery, gynecology, urology, colorectal and bariatrics.

Their skill with robotic technology offers patients better outcomes, including during laparoscopies—during which surgeons insert a camera through a small incision, limiting the procedure's invasiveness. For instance, only 0.2% of Dr. Chang’s laparoscopies for benign hysterectomies have escalated to open surgeries, which require larger incisions and longer recovery times. By committing to high surgical standards, Wellstar Cobb physicians minimize patient complications and readmissions.

“Wellstar Cobb continues to lead the way in robotic surgeries,” said Dr. Jody Hughes, chief medical officer at Wellstar Cobb. “Not only do we offer best-in-class services through technology like the DV5, but we also support other communities by helping train the next generation of elite robotic surgeons.”

Wellstar Kennestone Regional Medical Center has also acquired its own Da Vinci 5 Robot.
