These seemingly simple reactions are caused by a complex set of processes and interactions within the body. We asked dietitian Emer Delaney to explain how stress impacts our hormones, appetite, blood sugar levels and fat accumulation, as well as for tips for staying healthy during stressful times.</p>
<h2 class="p2"><b>What is stress?</b></h2>
<p class="p2">Stress is a natural response to the challenges and perceived threats we face in our day-to-day lives. We all experience stress to some degree.</p>
<p class="p2">There are many factors that may trigger stress; these include external pressures such as work or family responsibilities, and internal influences including what we eat and how our digestive, immune and nervous systems are working.</p>

<h2 class="p2"><b>How does stress affect our hormones?</b></h2>
<p class="p2">When in a state of stress, the body <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4867107/" target="_blank" rel="noopener"><span class="s3">triggers a small area at the base of the brain called the hypothalamus,</span></a> which sends signals to the adrenal glands (on the top of the kidneys) and pituitary glands (in the brain behind the nose).</p>
<p class="p2">The main stress hormones are:</p>
<h3 class="p2"><a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3056281/" target="_blank" rel="noopener"><span class="s3"><b>Adrenaline</b></span></a></h3>
<p class="p2">This hormone primes the body for the ‘fight or flight’ response – it does this by increasing blood pressure, heart rate and blood glucose levels. It also redirects blood from non-essential organs, such as the kidneys and skin, to the muscles and brain.</p>
<h3 class="p2"><b>Corticotrophin-releasing hormone (CRH)</b></h3>
<p class="p2">This <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2843773/" target="_blank" rel="noopener"><span class="s3">reduces appetite</span></a> and, in the long-term, triggers the body to release cortisol.</p>
<h3 class="p2"><a href="https://www.yourhormones.info/hormones/cortisol/" target="_blank" rel="noopener"><span class="s3"><b>Cortisol</b></span></a></h3>
<p class="p2">This affects a variety of processes in the body, including our blood sugar levels and metabolism. Read <a href="/howto/guide/how-to-lower-cortisol-levels" target="_blank" rel="noopener"><span class="s3">how to lower cortisol</span></a>.<b> </b></p>

<h2 class="p2"><b>How does stress affect my appetite?</b></h2>
<p class="p2">The impact of <a href="https://pubmed.ncbi.nlm.nih.gov/24126546/" target="_blank" rel="noopener"><span class="s3">stress on your appetite</span></a> varies, depending on whether it’s short or longer term.</p>
<p class="p2">Generally speaking, appetite is reduced in the early stages, because adrenaline causes a breakdown of glycogen and fat. This means your body has adequate fuel for the heart and muscles to work, which is useful in a ‘fight or flight’ situation. This results in a <a href="https://www.ncbi.nlm.nih.gov/pubmed/11732637" target="_blank" rel="noopener"><span class="s3">decreased appetite,</span></a> as blood is directed away from the digestive system. However, if the stress response is ongoing (such as in cases of long-term daily stress), cortisol levels increase and <a href="https://www.ncbi.nlm.nih.gov/pubmed/15460899" target="_blank" rel="noopener"><span class="s3">stimulate your appetite;</span></a> over time, this may lead to <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5373497/" target="_blank" rel="noopener"><span class="s3">weight gain</span></a>.</p>
<h2 class="p2"><b>How does stress affect blood sugar levels?</b></h2>
<p class="p2">Stress is often a cause of <a href="https://pubmed.ncbi.nlm.nih.gov/24126546/" target="_blank" rel="noopener"><span class="s3">high blood sugar levels;</span></a> this is a direct result of increased cortisol.</p>
<p class="p2">The reason cortisol influences the level of sugar (glucose) in the blood is because it signals the body to <a href="https://www.ncbi.nlm.nih.gov/pubmed/11724664" target="_blank" rel="noopener"><span class="s3">break down protein stores</span></a> in the liver. This process (called gluconeogenesis) creates glucose and, over time, may result in persistent high blood sugar levels. In response, the pancreas works hard to <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4892884/" target="_blank" rel="noopener"><span class="s3">regulate blood glucose levels</span></a> by producing more of the blood sugar-managing hormone insulin. If this continues over a long period of time, the body may become resistant to insulin – this is linked to <a href="https://www.diabetes.co.uk/insulin-resistance.html" target="_blank" rel="noopener"><span class="s3">type-2 diabetes</span></a>, <a href="https://pubmed.ncbi.nlm.nih.gov/32673836/" target="_blank" rel="noopener"><span class="s3">gestational diabetes</span></a> and <a href="https://pubmed.ncbi.nlm.nih.gov/18513304/" target="_blank" rel="noopener"><span class="s3">pre-diabetes</span></a>.</p>
<p class="p2"><b>For more information, check out the NHS website to learn more about</b> <a href="https://www.nhs.uk/conditions/high-blood-sugar-hyperglycaemia/" target="_blank" rel="noopener"><span class="s3"><b>hyperglycaemia</b></span></a> <b>(high blood sugar), and speak to your GP if you are concerned about your blood sugar levels.</b></p>
<h2 class="p2"><b>How does stress affect body fat?</b></h2>
<p class="p2">Persistently high levels of insulin caused by chronic stress can <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9362746/" target="_blank" rel="noopener"><span class="s3">increase abdominal weight </span></a>(belly fat) and overall weight. This happens as a result of an interaction that occurs in the body. There are three organs involved – the hypothalamus, pituitary and adrenal glands. We refer to this as the <a href="https://www.ncbi.nlm.nih.gov/pubmed/29719288" target="_blank" rel="noopener"><span class="s3">hypothalamic-pituitary-adrenal axis</span></a> (HPA).</p>
<p class="p2">When the HPA is activated by stress, it triggers the release of more cortisol and has been shown to play an <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4837456/" target="_blank" rel="noopener"><span class="s3">important role in body fat accumulation</span></a>. The result is an <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3498460/" target="_blank" rel="noopener"><span class="s3">increased appetite</span></a> and a reduced ability to break down food.</p>
<p class="p2">Stress can also slow metabolism making it harder to burn fat, especially belly fat, and stress may lower your ability to self-regulate your mood, making it harder to exercise and maintain healthy habits. Those who tend to carry more <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5958156/" target="_blank" rel="noopener"><span class="s3">weight in their upper body</span></a>, especially as <a href="https://pubmed.ncbi.nlm.nih.gov/9290093/" target="_blank" rel="noopener"><span class="s3">abdominal fat</span></a>, may find stress has a greater impact on their metabolism.</p>

<h2 class="p2"><b>Tips to manage stress</b></h2>
<h3 class="p2"><b>1. Be more active</b></h3>
<p class="p2">You don’t need to be a member of a gym to exercise – brisk <a href="/howto/guide/10-benefits-of-walking" target="_blank" rel="noopener"><span class="s3">walking</span></a> is a free activity you can introduce to your daily routine.

<h3 class="p2"><b>2. Try meditation</b></h3>
<p class="p2">Meditation can be a useful way to relax and calm down during times of stress. It doesn’t need to be for long periods; just taking a few minutes out of the day to switch off is enough to be beneficial.</p>
