When it comes to our health, we tend to rely on our own instincts to sense when something is wrong. There are, however, certain conditions develop in ways that make them difficult for an individual to notice, particularly when the symptoms occur while one is asleep or subtle behavioral changes. It is at such moments that your partner, who shares your space and knows one intimately, can be quite important in finding signs that may otherwise escape detection.The caring partner is not only a buddy—they can become a valuable helpmate in having good health. By noticing a subtle warning and urging medical examination, partners have the ability to detect and manage potentially serious health issues before life-threatening situations set in.If your partner mentions issues with your sleep habits, mood, or body changes, it's crucial to pay attention to what they are observing. Early detection can go a long way in treating conditions and avoiding complications later on.One of the most neglected yet severe health problems that a partner is most likely to detect is sleep apnoea—a sleeping disorder that stops and starts breathing, tending to result in serious health dangers. But outside of sleep patterns, there are many other illnesses where a second set of ears and eyes can be life-saving.What is Sleep Apnoea?Sleep apnoea is an intermittent cessation of breathing during sleep. Obstructive sleep apnoea (OSA) is the most prevalent type and results from an obstruction of the airway that limits airflow, causing temporary stoppages in breathing. Although the individual with sleep apnoea is not aware of these interruptions, a sleeping partner will observe characteristic signs such as:Repeated loud snoringGasps, chokes, or snortsExcessive awakenings during the nightAbnormal restlessness while asleepDaytime symptoms, including severe tiredness, headaches, poor concentration, and mood changes, can also suggest the existence of the condition. Sleep apnoea can cause high blood pressure, cardiovascular disease, stroke, and type 2 diabetes if left untreated.If your partner notices these symptoms, obtaining medical guidance and having a sleep study can result in a successful diagnosis and treatment plan, which may include lifestyle modifications, CPAP (Continuous Positive Airway Pressure) therapy, or surgery in extreme cases.Subtle Changes That May Signal Underlying IssuesOther than sleep disorders, a partner may also note gradual or sudden behavioral and appearance changes that may signal serious health issues. Examples of these are:1. Sudden Mood Swings and IrritabilityMood changes, heightened irritability, or depression signs sometimes indicate underlying illnesses like thyroid diseases, diabetes, or even neurological disorders like Parkinson's or Alzheimer's. If your partner points out extreme mood changes in you, it would be advisable to discuss the same with a healthcare professional.2. Skin Color or Texture ChangesYour spouse might be the first to spot slight changes in your skin, e.g., yellowing (indicative of liver disease), dark spots (which can signal insulin resistance or prediabetes), or abnormal moles (which could be early signs of skin cancer). Skin color change, chronic rashes, or spontaneous bruising should never be taken lightly and should be checked by a doctor.3. Frequent Night SweatsNight sweats are sometimes explained by stress or overheating, but regular night sweats might signal infections, endocrine imbalances, or even certain cancers such as lymphoma. If your partner points out that you're always waking up in sweat, a trip to the doctor is advised.4. Abnormal Breathing or Heart Rate While SleepingIf your partner observes pauses in your breathing beyond sleep apnoea or notices an irregular heartbeat when you’re at rest, this could indicate underlying cardiovascular issues. Atrial fibrillation (AFib) and other heart-related conditions often present with subtle symptoms that a sleeping or resting individual may not recognize but could be evident to a close observer.5. Significant Weight Loss or Gain Without ExplanationUnexplained fluctuations in weight accompanied by no diet or exercise plan change can signal thyroid dysfunction, diabetes, or even gastrointestinal diseases such as Crohn's disease or celiac disease. Your partner should get medical help investigated if they witness inexplicable fluctuations in weight.If your partner notices any of these symptoms, it's not good to brush off their worries. Most serious medical conditions are easiest to treat when they are diagnosed early. The following are what to do if a partner is concerned about your health:Maintain a Symptom Journal: Document any alterations in sleep, behavior, appetite, or body symptoms.Make an Appointment for a Medical Check-Up: Even when you are feeling well, a medical professional can conduct tests to eliminate any underlying causes.Undergo Diagnostic Testing: If symptoms are indicating problems such as sleep apnoea, diabetes, or heart disease, your physician may advise you to undergo a sleep study, blood work, or heart monitoring.Make Lifestyle Changes: Many of these conditions, including sleep apnoea and heart disease, can be alleviated by weight reduction, a healthy diet, and proper exercise.
