Investigate Shortness of Breath: Here's How
'All new episodes of shortness of breath should be evaluated in real time by a clinician, ideally in person,' said Panagis Galiatsatos, MD, MHS, pulmonologist and associate professor, Division of Pulmonary and Critical Care Medicine at Johns Hopkins School of Medicine in Baltimore.
But if the patient has a diagnosed condition, a phone or virtual discussion could be enough. 'The only time I can see foregoing an immediate clinic visit is if a known cardiopulmonary diagnosis exists,' Galiatsatos said.
For example, if you already know the patient has a pulmonary or cardiac condition and their dyspnea (shortness of breath) is similar to prior episodes of breathlessness, then an in-office appointment may not necessarily be needed, he said. Those could be managed by both an action plan that has already been discussed at prior visits.
A Red Flag During Office Visits
What if a patient is already in the office for another reason and casually mentions episodes of shortness of breath, how should the primary doctor proceed?
Panagis Galiatsatos, MD, MHS
Even if dyspnea is mentioned casually, it warrants a thorough history and focused physical exam, especially if this is new or worsening. This could be an early sign of a more serious problem, said Lijo Illipparambil, MD, pulmonologist and assistant professor of Clinical Thoracic Medicine and Surgery at the Lewis Katz School of Medicine at Temple University in Philadelphia.
When discussing such symptoms, Illipparambil recommends these questions:
When do episodes occur — during exertion vs rest?
How long have these symptoms been occurring?
Are there other symptoms, like fatigue, chest tightness, wheezing, cough, or swelling?
How limiting are the symptoms? Is the patient able to climb stairs, and if so, how many? Is walking across a room or doing daily chores causing them to be dyspneic?
How to Be a Frontline Partner?
Primary care doctors are essential in identifying early signs of cardiopulmonary disease.
'Generally, they are the first physicians who meet the patients and do most of the work-up initially. They coordinate care, especially with specialists, provide lifestyle counseling, and monitor chronic conditions like COPD [chronic obstructive pulmonary disease], asthma, and congestive heart failure,' Illipparambil said.

In many ways, they are the real central component for care of patients with dyspnea, he affirmed. 'They also have the advantage of longitudinal relationships, allowing them to notice changes over time and engage in shared decision-making to create sustainable health strategies and earlier intervention if needed,' Illipparambil said.
Assessment Protocol
Usually, a thorough physical exam, including checking vital signs, especially oxygen saturation and heart rate, is next, Illipparambil said. And additional testing should be considered including chest x-ray, EKG, and laboratory work-up, as well as referral to specialists if warranted.
Red flags that warrant further testing include:
Dyspnea at rest is always a reason for further testing, he said. 'It is not normal to be short of breath at rest; it is most often a sign of significant impending decompensation. Additionally, Illipparambil said, worsening shortness of breath over days/weeks can demonstrate a progressive process. Difficulty walking short distances or performing basic activities (eg, walking in the supermarket, pushing a stroller), especially as a change from their baseline, can be a sign of an active problem.
Orthopnea or paroxysmal nocturnal dyspnea are signs of heart failure that need further investigation.
Unilateral leg swelling should always have a differential that includes deep venous thrombosis and possible pulmonary embolism if present when a patient is short of breath, he said.
Expert Assessments and Symptoms
Consider the shortness-of-breath assessments below, according to Galiatsatos:
Airway diseases. COPD or asthma are examples. 'I would recognize due to inability to walk incline or when holding groceries — not walking through the grocery store, but once their arms are engaged, their breathlessness is noticeable,' he explained.
Cardiac rhythm issues (especially low heart rates). Most people notice this breathlessness even within a few dozen feet or so of walking on flat surface, he cited.
Pulmonary embolism (lung blood clot). This is more acute in occurrence, and patients often describe a heaviness and uncomfortableness in their chest. 'This is often accompanied by something that provoked the blood clot, long hours of sitting say from a long flight, or a trauma to the legs,' Galiatsatos continued.
Heart failure. The key symptom here is the inability to lay down flat, he asserted. Patients may note having to sleep with several pillows, prompting their head and upper torso to be more and more vertical or abandoning sleeping in a bed and sleeping in a recliner, he also explained.
Lifestyle Strategies
The key is to be empathetic, collaborative, and goal oriented.
'This is indeed a delicate yet vital conversation,' Illipparambil said. There are several reasons for shortness of breath and approaching patients this way can help with patient openness and discussion. One thing that helps is the use of motivational interviewing techniques. For instance, he recommends asking permission to discuss weight, tobacco use, or other lifestyle habits that may be affecting shortness of breath can help establish a partnering role in these goals.
Another way to approach, he continued, is focusing on functions such as walking without getting winded and changing habits toward a healthy lifestyle rather than just the number on the scale.
'Additionally, offering resources and referrals for nutrition, sleep study, physical therapy, etc., can go a long way. Medications, of course, can help, especially inhalers in COPD and asthma patients. Antihypertensives and other medications that help modify heart disease, and goal-directed medical therapy have been shown to improve symptoms in patients with heart failure,' Illipparambil also said.
How Does Obesity Intersect With Shortness of Breath?
Obesity is often linked to cardiopulmonary deconditioning, according to Trishul Siddharthan, MD, pulmonologist and associate professor of the Department of Medicine with the University of Miami Miller School of Medicine and the UHealth — University of Miami Health System, both in Miami.
'Extra weight is a significant cause of shortness of breath in the general population and interacts with respiratory diseases like asthma to worsen symptoms,' Siddharthan outlined.
Lifestyle changes and other strategies to cope are a shared decision, he said. 'I ensure I address the underlying medical condition while addressing enablers and barriers to weight loss.'

RFK Jr's MAHA tour branded 'performative'
Robert F Kennedy, Jr's (RFK Jr) statewide tour promoting his Make America Healthy Again (MAHA) agenda has been called 'performative' by a US health consultancy. Since taking an axe to the health agencies nested under the US Department of Health and Human Services (HHS) in April, RFK Jr has toured states, including Colorado and Idaho, to promote his MAHA agenda. According to the White House's MAHA report, a key tenet of the initiative is to assist President Trump in addressing what the US health secretary has called the 'childhood chronic disease crisis', and includes vague aims to deliver more nutrient-dense food to the US population. Wellness Equity Alliance CEO Dr Tyler B Evans told Medical Device Network: "What we're witnessing with RFK Jr's roadshow is not leadership, it's theatre. 'The health secretary is cloaking vague rhetoric under the MAHA banner and selling it as reform, but the movement lacks policy substance and remains disconnected from the realities of public health. At best, it's a distraction. At worst, it's a dangerous misdirection that erodes trust in the institutions we need the most.' In April, RFK Jr delivered a speech at the US Food and Drug Administration (FDA), coinciding with the announcement of 10,000 planned job cuts across health agencies, including the FDA and the National Institutes of Health (NIH). The 40-minute speech included a range of baseless claims on various topics, according to a transcript of the speech seen by Politico. During his speech, RFK Jr stated that 'this whole generation is damaged' and claimed that rising rates of chronic disease, allergies and other illnesses were attributable to 'some environmental toxin'. How effective leadership at the HHS should look Evans emphasised that leadership at the HHS should be grounded in science, transparency, and accountability. 'It requires listening to public health professionals, not sidelining them, and to prioritise data over disinformation,' Evans said. 'I've worked on pandemic responses, from Ebola in West Africa to HIV/AIDS in South Africa to Covid-19 in NYC. What I've learned is simple: when health leadership is weak or politicised, people die unnecessarily. RFK Jr's decision to dismantle the department's capacity, especially during ongoing public health crises, is not reform. It is sabotage.' RFK Jr's MAHA tour has continued through July following the passage of Trump's 'One Big Beautiful Bill Act', which the Congressional Budget Office (CBO) estimates will leave 11.8 million people without health insurance by 2034. In a post to X following the bill's success in the Senate, Democratic senator Alexandria Ocasio-Cortez called the outcome 'an absolute and utter betrayal of working families'. To best serve the US's health, Evans said RFK Jr should focus on rebuilding trust with those most harmed by systemic neglect and called the current outcomes under the health secretary's leadership 'deeply troubling'. Evans concluded: 'Rebuilding trust requires investing in public health infrastructure, supporting workforce development, and addressing social determinants like housing, education, and food security. A national tour is not a substitute for that kind of real work.' "RFK Jr's MAHA tour branded 'performative'" was originally created and published by Medical Device Network, a GlobalData owned brand.

5 Supplements That Don't Mix Well with Coffee, According to Pharmacists
Reviewed by Dietitian Maria Laura Haddad-GarciaKey Points Coffee may reduce the absorption of iron, calcium, magnesium and some vitamins. Wait at least 1 hour after coffee to take supplements for better nutrient uptake. Not everyone needs supplements—talk to your provider before adding them to your you're the kind of person who can't start their day without a cup (or two) of coffee, you're not alone. Coffee is a staple morning ritual—whether it's sipped alongside breakfast, before a workout or first thing after waking up, that morning brew helps us feel energized and ready for the day. But if you also take vitamins or minerals as part of your morning routine, it's worth knowing how coffee might influence how your body absorbs those nutrients. Caffeine, polyphenols and coffee's mild diuretic effect can interfere with how your body uses certain vitamins and minerals. "For instance, iron absorption can be slowed by caffeine and caffeine can impact certain nutrients via its diuretic properties," says Philip Ngo, Pharm.D. We spoke with pharmacists to understand how coffee can impact nutrient absorption—and what you can do to get the most from your supplements. 1. Iron Iron is essential for growth, hormone production and cellular function. And it's a common nutrient deficiency, so your healthcare provider may have suggested supplementing. "Having coffee with an iron supplement or fortified cereal may make your body absorb less iron," notes Bo Wang, M.D., Pharm.D. "Over time, a heavy caffeine habit could potentially impact bone and mineral health." One study found that drinking coffee with iron reduced absorption by 54%. Pairing it with breakfast further lowered absorption. This interaction isn't about the caffeine—it's due to chlorogenic acid, a polyphenol in coffee and tea. "This compound is a strong inhibitor of non-heme iron absorption (the type found in plant foods and supplements)," adds Elise Kim, Pharm.D., BCACP, CDCES, AHSCP-CHC. Researchers believe that the polyphenols may impact the way our gut absorbs iron. Wang recommends separating iron from coffee by at least one hour and pairing it with vitamin C-rich foods, such as lemons and oranges, to enhance absorption. 2. Vitamin D Vitamin D is a nutrient that is hard to get through diet alone, since it's not naturally found in many foods. However, our bodies can also make vitamin D from sunshine. "Research suggests that caffeine may reduce the expression of vitamin D receptors, which can lower vitamin D levels," says Kim. "However, its clinical impact is still being studied." A 2021 study linked higher caffeine intake with lower circulating levels of vitamin D, though more research is needed. To get the most from your supplement, consider spacing it at least an hour away from your coffee, Ngo suggests. And since vitamin D is fat-soluble, taking it with a meal that includes healthy fats can help improve absorption. 3. B Vitamins This group of water-soluble vitamins—including B1, B2, B7, B9 and B12—supports energy production, nerve function and red blood cell formation. Water-soluble vitamins dissolve in water, and our bodies cannot store a lot of excess at one time. "As B vitamins are water-soluble, caffeine's mild diuretic effect can increase how much your body excretes, especially with higher caffeine intake," says Kim. Studies show that people who drink coffee tend to have lower levels of circulating B vitamins, likely due to urinary losses. 'Avoid taking supplements with coffee or tea," advises Wang. "Wait an hour if you can. Water-soluble vitamins (C, Bs) are fine with or without food, but may go down easier after a meal." 4. Magnesium Magnesium is an important mineral that plays a role in protein synthesis, blood sugar management, blood pressure regulation and sleep quality. While it's found in foods like beans, nuts and yogurt, many people don't get enough from diet alone. "Caffeine can increase calcium and magnesium loss through urine," notes Kim. If you're taking magnesium as part of a nighttime routine—a common supplement to help you sleep better—it's best to avoid caffeine close to bedtime. Not only can caffeine interfere with sleep, but it may also reduce magnesium's effectiveness in promoting deeper rest. 5. Calcium Just like magnesium, calcium may be impacted by coffee's diuretic effects. "Calcium absorption may be reduced by caffeine, but the clinical impact remains unclear," says Kim. A study showed that participants who consumed caffeine had 77% more calcium excreted by their kidneys compared to a placebo group. Adding milk to your coffee may help offset calcium loss, and spacing out calcium supplements at least one hour after your coffee—or two hours before—can help support better absorption, suggests Kim. Our Expert Take Coffee can influence how your body absorbs certain nutrients, but simple timing tweaks can help. Spacing out your supplements from coffee by an hour can support better absorption. If you occasionally forget and take them together, you'll still likely absorb some nutrients. And in spite of what you may see being pushed by wellness influencers, not everyone needs supplements. "Supplements are just that—to supplement," says Ngo. "For a person in good general health who consumes a balanced diet, it may not be worth investing in supplements unless you are truly deficient." Chatting with a health care provider and lab testing can help determine what's best for you. Read the original article on EATINGWELL
