Understanding the toll acid reflux can take on your health

February 26, 2025

How lifestyle choices can help manage GORD  

What happens when the hydrochloric acid produced in the stomach escapes upwards into a person’s oesophagus? A bitter taste in the mouth, heartburn, sore throat, hoarse voice or unexplained chronic cough can be tell-tale signs of the acidic burn of reflux or the longer-term condition gastroesophageal reflux disease (GORD).

 

“The troublesome symptoms people with GORD experience can have significant social, workplace, and economic impacts, especially when the condition is persistent and chronic. It’s also one of the most common conditions primary healthcare physicians and gastroenterologists are consulted for,” says Dr Barbara Makumbi, a gastroenterologist practising at Netcare Sunward Park Hospital.



“Typically, when we eat, food passes down the oesophagus and enters the stomach through the lower sphincter, which functions as a one-way valve to seal the stomach and prevent digestive contents from flowing back into the oesophagus. However, in some cases – especially after eating certain foods, or when lying down soon after a meal – the pressure in the stomach can increase, causing the acidic liquid to escape from the stomach upwards, irritating the more sensitive lining of the oesophagus and leading to discomfort,” she explains.

Dr Makumbi points out that the symptoms of reflux can be sporadic and mild for some people, but may develop into a progressively worse chronic condition, known as GORD, if not addressed. “Over time, this unconscious regurgitation causes inflammation that can make eating or its after-effects quite painful, disrupt the person’s sleep, and potentially lead to other troubling complications,” she cautions.

 

Recognising GORD

Dr Makumbi says there are various possible symptoms associated with reflux and gastroesophageal reflux disease (GORD).

 

Typical symptoms

  • Heartburn is a burning sensation usually felt in the centre of the chest that often occurs after meals and worsens when lying down.
  • Regurgitation – When the digestive fluid comes up the oesophagus, this can result in a bitter taste in the mouth.
  • Belching (burping)
  • Nausea or vomiting
  • Experiencing a sensation of fullness sooner when eating.

 

Dr Makumbi says that in more severe cases, complications involving damage to the oesophagus and nearby anatomy can result in atypical symptoms, including the following:

  • Inflammation of the lining of the oesophagus leading to difficulty swallowing or painful swallowing and bleeding.
  • Laryngitis or pharyngitis: Throat inflammation resulting in a sore throat or hoarse voice.
  • Small amounts of the acidic gastric fluid can enter the airways of the lung, resulting in chronic cough, new or worsening asthma and scarring of the lung tissue called fibrosis.
  • Dental complications can occur when the teeth are exposed to regurgitated stomach acid, including erosion of tooth enamel, tooth decay and bad breath.

 

Dr Makumbi encourages anyone experiencing persistent symptoms of reflux or GORD to consult a healthcare practitioner for a diagnosis and appropriate treatment.

 

GORD risk factors may include:

  • Structural changes to the sphincter muscle, such as a hiatus hernia, where the stomach bulges into the chest above the diaphragm
  • Abdominal fat, weight gain, or being overweight or obese
  • Pregnancy
  • Diet and habits that can weaken the oesophageal sphincter, including fatty foods, caffeine, smoking, alcohol, and carbonated drinks
  • Certain medications’ side effects
  • Having large meals or eating too close to bedtime

 

“If GORD is not identified and managed, either through lifestyle modification alone or in combination with medication, the person may be at risk of developing oesophageal strictures. This is where, over time, the lining of the oesophagus is repeatedly irritated and inflamed and develops scar tissue, which can narrow the passage that conveys food from our mouths to our stomachs, making it difficult to swallow.

 

“Another important reason to get reflux addressed is Barrett’s Oesophagus, which is a precancerous lesion of the lower part of the oesophagus that is associated with repeated acid exposure. As the disease progresses, Barrett’s can develop into oesophageal cancer.

 

“Be sure to inform your doctor if you have a family history of oesophageal or stomach cancer, as this can also suggest a need for heightened vigilance,” she advises.

 

Some patients may require further investigation with a gastroscopy, where a gastroenterologist or surgeon uses a long thin tube with a camera to check the mouth, oesophagus, stomach and duodenum. Other times, a barium swallow in a radiology department may be requested, where the patient drinks a contrast fluid to reveal the swallowing mechanism and the anatomy of the oesophagus and stomach.

 

“In severe cases, reflux monitoring and pH studies can be done, whereby a catheter is inserted via the nostrils into the oesophagus to monitor the amount of reflux and the acidity of the digestive contents to confirm and classify diagnosis of GORD,” Dr Makumbi explains.

 

“Lifestyle modification is important for management of GORD, and a few simple steps can often help bring significant relief for mild to moderate cases,” she says.

 

Tips for coping with GORD

  • Elevate your head and upper body with a few extra pillows when you sleep. This allows gravity to assist in reducing reflux.
  • Shedding excess kilos can help reduce upward abdominal and gastric pressure that contributes to reflux.
  • Try sleeping on your left side.
  • Eat dinner three hours before bedtime.
  • Avoid lying down after meals.
  • Avoid alcohol and smoking.
  • Reduce the size of meals.
  • Consult a dietician and avoid fat, citrus, spicy food, tomato-based products, chocolate, peppermint, and caffeinated or fizzy drinks.
  • Keep a food diary to help identify your individual triggers.

 

“Most cases of GORD can be effectively managed with these principles, and over-the-counter short-term relief or prescription medications as needed. Surgical options may be considered for certain patients whose conditions are severe. However, these procedures are not undertaken lightly. Nowadays, such procedures are usually performed laparoscopically, or with a ‘pinhole’ surgery approach,” Dr Makumbi concludes.

Rare Disease Day on 28 February 2025
February 28, 2025
The lives of millions of South Africans with a litany of rare diseases can be vastly improved, and even saved, by addressing challenges in identifying, studying and treating their conditions. With Rare Disease Day on the 28th of February 2025, the Rare Diseases Access Initiative (RDAI) is driving an evolution of the country’s healthcare, through innovative strategies to better care for over 4.2million people living with an estimated 7000 rare diseases. “As our healthcare system faces significant changes in the years ahead, it is vital that we also advocate for people living with rare diseases in South Africa, especially those with limited healthcare access,” said Kelly du Plessis, CEO of Rare Diseases South Africa (RDSA), a member of RDAI. “As part of our ongoing research and awareness efforts, RDAI has conducted an initial analysis of the incidence and prevalence of rare diseases within the country.” This research will assist in improving access to healthcare, policy development, and patient advocacy, while giving critical insight into the challenges faced by patients. “According to research, some rare diseases affect fewer than 1 in a million people, while others, such as Down syndrome, cystic fibrosis, and haemophilia, have a more recognisable prevalence,” says Dr. Helen Malherbe, RDAI lead researcher on rare disease prevalence data. “Many conditions are undetected, underdiagnosed or misdiagnosed, with too many having no information available about them at all.” The RDAI was formed in 2019 to promote a more favourable environment for those impacted by rare diseases in South Africa. Participants include Ampath, the Board of Healthcare Funders (BHF), Discovery Health, Genetic Counsellors South Africa (SASHG), the Government Employees Medical Scheme (GEMS), Health Funders Association (HFA), Medihelp, Medscheme, North-West University (NWU), Rare Diseases South Africa (RDSA), the South African Medical Association (SAMA) and The South African Medical Technology Industry Association (SAMED). The Council for Medical Schemes (CMS) participates as an observer. In the same year, Rare Disease International signed a memorandum of understanding with the World Health Organisation leading to an international rare disease policy framework. In 2021, the United Nations General Assembly moved to adopt a resolution recognising 300 million people living with rare diseases worldwide. “A general lack of awareness and delayed diagnosis remain major hurdles for those affected by rare diseases. Policymakers and healthcare stakeholders need to prioritise access to treatment, diagnosis, and support for rare disease patients,” says Bada Pharasi, CEO of IPASA, “Through this initiative, working collaboratively with stakeholders at every level of the healthcare supply chain, we can bring real and meaningful change to those affected, including family members and care givers, through smart and efficient strategies.” The globally agreed definition of a rare disease is any medical condition with a specific pattern of clinical signs, symptoms, and findings that affects fewer than or equal to 1 in 2000 persons in a population. “Most are genetic, and some are inherited and passed down in families,” Malherbe says. “Some affect only the patient’s genetic recipe, while others may be acquired during life due to infection, trauma, or environmental effects. For many, the cause is still unknown. “These conditions mainly affect children, as they are largely incurable and many are life-threatening. Some require specialised and co-ordinated care, some have limited and expensive treatment options, while others have no information or effective treatments at all,” she adds. The RDAI is calling for a patient-centred care model built on equitable access, transparency and efficiency. Naturally, this model calls for the open participation of patients, the healthcare industry, health professionals, and the Government. “The most critical elements are robust diagnosis standards, improved access to treatment, data collection and management, co-ordination of care, measurement of outcomes and ongoing collaborative research,” du Plessis says. “We need to establish rare disease advisory committees, map gaps and opportunities, establish system requirements, create a roadmap and plan a phased implementation with clear timelines.” The RDAI states that these policy development steps would be a start in quantifying the disease burden and defining standards of care. This would be followed by building and strengthening the capacity to facilitate appropriate diagnosis, treatment, continuity and data monitoring. Thoneshan Naidoo, Chief Executive Officer of the Health Funders Association noted that, “We appreciate the unique opportunity provided by RDAI which enables stakeholders across the industry to work together and identify strategies that improve equitable access to the appropriate diagnosis, treatment and healthcare services for rare disease patients, in an affordable and sustainable manner, taking account of the other pressing needs across the healthcare system.” “True innovation in healthcare is only possible through partnerships and joint advocacy efforts that raise awareness and improve access to treatment. Our long-term goal is the development of a rare diseases policy framework and guidelines for coordinated care,” says Pharasi. “Our members are united in the commitment to unlocking improved patient outcomes and improving access to services and robust health needs assessment facilities.” he concludes. About RDAI The Rare Diseases Access Initiative (RDAI) is dedicated to advocating for improved healthcare access, policy development, and patient support for those affected by rare diseases in South Africa. The initiative brings together key healthcare stakeholders, including pharmaceutical associations, funders, genetic specialists, and patient advocacy groups, to drive impactful change. About RDSA Founded in 2013, Rare Diseases South Africa (RDSA) is a non-profit organisation advocating to ensure that people living with rare diseases and congenital disorders experience greater recognition, support, improved health service and better overall quality of life. Started out of personal need following the diagnosis of organisation founder, Kelly du Plessis' son, it became evident that there was a lack of awareness and support for rare diseases in general in South Africa. About IPASA The Innovative Pharmaceutical Association South Africa (IPASA) is a voluntary trade association representing 24 leading pharmaceutical companies committed to research, development, and innovation. Our mission is to drive healthcare advancement by advocating for policies that improve patient access to safe, high-quality, and affordable medicines.
