The link between obstructive sleep apnea and weight gain

Mar 24, 2023

Are you having trouble sleeping at night? Do you feel like no matter what you do, the pounds just keep creeping up, even though your diet and exercise regimen haven't changed? If so, then it’s possible that you may be suffering from obstructive sleep apnea (OSA). OSA is a condition in which your airway repeatedly collapses during sleep, causing pauses in breathing and reducing the amount of oxygen reaching your brain. Both short-term and long-term effects can include weight gain due to increased hunger caused by less restful sleep; this leads to metabolic syndrome, which has been linked with an elevated risk of developing cardiovascular disease. 


OSA can create a problematic cycle where weight gain triggers more sleep apnea and vice versa.

Recognizing the signs of OSA is important, as they include excessive daytime sleepiness, snoring, awakening with a dry mouth or sore throat, and morning headaches. Regular exercise, maintaining a balanced diet, avoiding large meals before bed, quitting drinking and smoking, and reducing stress levels are all ways to help manage OSA and prevent weight gain.


In this blog post, we will explore the link between OSA, weight gain, and metabolic syndrome in more detail.

What is obstructive sleep apnea (OSA)?

Obstructive sleep apnea (OSA) is a condition where there’s a temporary cessation of breathing during sleep due to an obstructed airway. People who suffer from OSA will have recurring pauses in their breathing when sleeping, which can last from several seconds to minutes. These pauses can occur hundreds of times throughout the night and often result in very fragmented and light sleep. In addition, those with OSA may also experience loud snoring due to their gasping for air throughout the night. It affects around 18 million people in the U.S., and research has indicated that it may be linked to weight gain, metabolic syndrome, and other serious medical problems such as stroke and heart disease.

How OSA affects your body weight

Obstructive sleep apnea (OSA) is an increasingly common condition that can have serious long-term effects on your health. One of these effects, often overlooked, is the way it affects your body weight and metabolism. OSA can lead to a problematic cycle where weight gain triggers more sleep apnea, and sleep apnea causes further weight gain. OSA may also be a symptom of metabolic syndrome, which is a collection of health problems like high blood pressure and high cholesterol brought on by poor lifestyle choices or genetics. So if you're finding yourself gaining weight, even when following diet and exercise programs, it's important to speak with Dr. Lillenberg about your treatment options —it could save your life.

What is metabolic syndrome and how is it related to OSA and weight gain?

A metabolic syndrome is a group of risk factors that can significantly increase your chances of developing type 2 diabetes, stroke, and heart disease. It also contributes to weight gain and is frequently associated with obstructive sleep apnea (OSA). The biological causes are intricately tied together; having an increased body mass index (BMI) places a higher strain on the heart, raising the risk for OSA due to a narrowed airway. Furthermore, OSA decreases respiration while sleeping, leading to reduced oxygen in the blood, which results in alterations to metabolism and hormonal changes influencing hunger and cravings. As this behavior continues and becomes a cycle, it’s easy to understand how metabolic syndrome and weight gain gradually become inevitable as time goes on. Unfortunately, this can lead to other medical issues beyond those associated with metabolic syndrome, but fortunately, there are ways you can break the cycle or prevent it from happening at all.


How can you recognize the signs of OSA?


Recognizing the signs of obstructive sleep apnea can be a tough task, but understanding the symptoms is half the battle. Pay attention to frequent shifts in breathing during sleep or lots of snoring; these two factors can be surefire indicators of OSA. 

Obstructive sleep apnea symptoms include:

  • Excessive daytime sleepiness
  • Snoring incessantly
  • Abrupt awakenings accompanied by gasping or choking
  • Awaking with a dry mouth or a sore throat
  • Morning headache
  • Trouble concentrating during the day
  • High blood pressure
  • lowered libido


If you suspect you might have it, remember you can come and speak with Dr. Lillenberg; he will be able to provide the best treatment plan possible.

Tips for managing your sleep apnea and preventing weight gain

As we all know, OSA causes disrupted sleep, but it can also lead to weight gain if left untreated. To keep your OSA and weight in check, follow some simple principles, such as: 

  • Exercising frequently
  •  Maintain balanced diet
  •  Avoiding large meals before bed
  • Quit drinking and smoking
  • Avoid taking sleeping pills
  • Avoid caffeine before bed

Additionally, managing stress levels is also strongly linked to better sleep patterns. Working with your primary care doctor and Dr. Lillenberg on how to best manage this high-risk condition may be beneficial in minimizing the risk of both weight gain and sleep disruption.


OSA is strongly related to weight gain, especially when combined with metabolic syndrome. If you think you may be suffering from sleep apnea, book a consultation to speak with Dr. Lillenberg today and get your treatment started on the path to better health. With his help, you can rest easy knowing that this condition will become more manageable and that you will remain healthy for years to come!
