Find out in this article.<\/p>\n<h2>When do symptoms of lactose intolerance appear?<\/h2>\n<p>After consuming lactose, symptoms generally appear <strong>between 15 minutes and 6 hours<\/strong>. It all depends on the amount eaten, the type of meal and individual sensitivities. Some people feel <a href=\"https:\/\/www.lactolerance.fr\/blog\/en\/bloating\/\"  data-wpil-monitor-id=\"74\">bloating<\/a> very quickly, while others only feel the effects during the night or the following morning.<\/p>\n<h2>How long does an attack of lactose intolerance last?<\/h2>\n<p>The duration of an attack varies. On average, an attack of lactose intolerance may last <strong>a few hours to 24 hours<\/strong>. In some very sensitive people, digestive discomfort may persist for longer, up to <strong>48 hours<\/strong>especially if a large amount of lactose has been consumed.<\/p>\n<h2>Why does the duration vary from person to person?<\/h2>\n<p>Several factors influence the duration of a crisis:<\/p>\n<ul>\n<li><strong>The amount of lactose ingested<\/strong> The higher the dose, the longer the symptoms.<\/li>\n<li><strong>Speed of intestinal transit<\/strong> Slow transit can prolong discomfort.<\/li>\n<li><strong>Individual sensitivity<\/strong> Some people react to very small doses.<\/li>\n<li><strong>The type of food eaten with <a href=\"https:\/\/www.lactolerance.fr\/blog\/en\/le-lactose\/\"  data-wpil-monitor-id=\"75\">lactose<\/a><\/strong> Dairy products eaten on their own often provoke a faster and more intense reaction.<\/li>\n<\/ul>\n<h2>What are the most common symptoms during a seizure?<\/h2>\n<p>Attacks of lactose intolerance often result in :<\/p>\n<ul>\n<li>bloating,<\/li>\n<li>abdominal cramps,<\/li>\n<li>accelerated or slowed transit,<\/li>\n<li>feeling of heaviness in the digestive tract,<\/li>\n<li>sometimes severe fatigue linked to digestion.<\/li>\n<\/ul>\n<h2 data-start=\"1274\" data-end=\"1330\">Is a crisis of intolerance dangerous?<\/h2>\n<p data-start=\"1333\" data-end=\"1682\">No. An attack of lactose intolerance is unpleasant but <strong data-start=\"1394\" data-end=\"1410\">not serious<\/strong>. It does not cause lesions or long-term complications. It is a <strong data-start=\"1488\" data-end=\"1511\">functional disorder<\/strong> linked to poor digestion of lactose. On the other hand, if the symptoms are very frequent or intensify, it is better to c<strong>onsult a healthcare professional<\/strong> to rule out another digestive cause.<\/p>\n<h2>What can be done to shorten the duration of a crisis?<\/h2>\n<p>If a crisis does occur, there are unfortunately no <strong>no miracle solution to stop it immediately<\/strong>However, there are a few things you can do to ease the discomfort and speed up the return to normal:<\/p>\n<ul>\n<li>Drink lukewarm water regularly,<\/li>\n<li>Eat light meals (rice, cooked vegetables, bananas),<\/li>\n<li>Avoid dairy products and fatty dishes while you recover,<\/li>\n<li>apply a hot water bottle to the stomach to relieve cramps.<\/li>\n<\/ul>\n<h2>How can we prevent future crises?<\/h2>\n<p>The best way to reduce the duration and intensity of a crisis is to avoid them in advance. To do this, you can :<\/p>\n<ul>\n<li>choose lactose-free products,<\/li>\n<li>prefer mature cheeses, which are naturally low in lactose,<\/li>\n<li>take a lactase supplement such as <strong>LACTOLERANCE<\/strong> before eating a meal containing lactose to ensure optimal digestion.<\/li>\n<\/ul>\n<h2>Summary<\/h2>\n<p>An attack of lactose intolerance lasts on average from a few hours to 24 hours, sometimes up to 48 hours depending on sensitivity and the amount ingested. Although it can't be stopped instantly, there are a few things you can do to make it easier to cope.
