| <!-- ====== WHY A GLUCOSE MONITOR ====== --> | |
| <h2>Why a Glucose Monitor?</h2> | |
| <p>When you eat, your blood sugar rises. Some foods cause a sharp spike followed by a crash — that crash is what makes you feel exhausted, foggy, and reaching for more sugar. A continuous glucose monitor (CGM) shows you this in real time, so you can learn which foods give you steady energy vs. which ones crash you.</p> | |
| <p>During pregnancy, your body becomes more insulin resistant (especially in the second and third trimesters), which means glucose spikes can be more pronounced. Understanding your personal patterns can help you:</p> | |
| <ul> | |
| <li><strong>Find foods that give you sustained energy</strong> instead of crashes</li> | |
| <li><strong>Identify "healthy" foods that secretly spike you</strong> (oatmeal and sweet potatoes are common surprises)</li> | |
| <li><strong>Feel more in control</strong> of your body during a time when a lot feels out of control</li> | |
| <li><strong>Learn simple tricks</strong> like eating protein before carbs, or walking 10 minutes after a meal</li> | |
| </ul> | |

| <thead> | |
| <tr><th></th><th>Dexcom Stelo</th><th>Abbott Lingo</th></tr> | |
| </thead> | |

| </table> | |
| <p>Stelo wins on everything that matters: it's explicitly pregnancy-safe, more accurate, more waterproof (baths!), and lasts longer. Lingo is $6 cheaper and reads slightly more often, but accuracy and safety matter more.</p> | |
| <h3>The App: Levels Health</h3> | |
| <p>The Stelo app shows you your glucose graph but doesn't score your meals or tell you what to change. Levels fills that gap:</p> | |
| <ul> | |
| <li><strong>Meal scoring (1-10):</strong> Levels grades your meal based on your glucose response AND the food quality. Scores of 7+ mean you're in good shape.</li> | |
| <li><strong>Food logging made easy:</strong> Take a photo, scan a barcode, or just say what you ate (voice input). When you're exhausted, talking is easier than typing.</li> | |
| <li><strong>Meal comparison:</strong> See two meals side by side with their glucose curves. "How did today's breakfast compare to yesterday's?"</li> | |
| <li><strong>Smart recommendations:</strong> If bread spikes you, it suggests sourdough or high-protein wraps instead.</li> | |
| <li><strong>NOT about weight loss.</strong> Levels focuses on metabolic health and energy — the right frame for pregnancy.</li> | |
| </ul> | |
| <!-- ====== PREGNANCY SAFETY ====== --> | |
| <h2>Pregnancy Safety</h2> | |
| <div class="safety-box"> | |
| <p><strong>Dexcom Stelo FAQ explicitly says:</strong> "Yes, you can use Stelo if you're not on insulin and you're not at risk of hypoglycemia." Pregnancy is not a contraindication.</p> | |
| </div> | |
| <ul> | |
| <li><strong>CGMs have been studied in pregnant women</strong> with type 1, type 2, and gestational diabetes and found safe and accurate. Multiple published studies support this.</li> | |
| <li><strong>CGMs are used "off-label" in pregnancy</strong> — the FDA hasn't specifically approved them FOR pregnancy, but they're not restricted. This is normal for many devices.</li> | |
| <li><strong>Skin reactions are more common during pregnancy</strong> — about 48% in one study experienced some reaction (redness, dry skin). Try a skin barrier wipe before applying, or switch arms.</li> | |
| <li><strong>Sensor placement:</strong> Back of your upper arm (NOT belly). Place it on the arm you don't sleep on to avoid false low readings from pressure.</li> | |
| <li><strong>Won't interfere with your glucose tolerance test</strong> — the CGM reads interstitial fluid, not blood. Your GD screening is a blood draw and works independently.</li> | |
| </ul> | |
| <div class="warning-box"> | |
| <p><strong>Talk to your OB before starting.</strong> Not because there's a safety concern, but because they should know and can help interpret the data.</p> | |
| </div> | |
| <!-- ====== FIRST 2 WEEKS ====== --> | |
| <h2>What to Expect in the First 2 Weeks</h2> | |
| <div class="timeline"> | |
| <div class="timeline-item"> | |
| <h3>Days 1-3: Just Watch</h3> | |
| <p>Don't change anything. Eat your normal foods. The goal is to see your baseline — what your glucose does right now.</p> | |
| </div> | |
| <div class="timeline-item"> | |
| <h3>Days 4-7: The "Aha Moments"</h3> | |
| <p>This is when it gets interesting. Most people discover:</p> | |
| <ul> | |
| <li><strong>"Healthy" foods that spike them.</strong> Steel-cut oats, sweet potatoes, smoothie bowls, and rice are common surprises. One woman discovered her daily turmeric oat milk latte spiked her to 165 mg/dL — "rivaling eating candy."</li> | |
| <li><strong>Foods they expected to spike that don't.</strong> Popcorn barely moves the needle. Dark chocolate is often fine.</li> | |
| <li><strong>The stress connection.</strong> You might see your glucose spike during a stressful moment with no food. Stress hormones raise blood sugar.</li> | |
| </ul> | |
| </div> | |
| <div class="timeline-item"> | |
| <h3>Days 8-14: Experiment</h3> | |
| <ul> | |
| <li>Eat the same meal but add an egg and cheese first → watch the spike shrink</li> | |
| <li>Take a 10-minute walk after dinner → watch the spike disappear</li> | |
| <li>Try sourdough instead of regular bread → compare the curves</li> | |
| <li>Eat dinner an hour earlier → see how it affects overnight glucose</li> | |
| </ul> | |
| </div> | |
| <div class="timeline-item"> | |
| <h3>After 2 Weeks</h3> | |
| <p>You'll know your body's patterns. Most people learn the key lessons in 2-4 weeks. Budget for 1-2 months — you don't need to wear it forever.</p> | |
| </div> | |
| </div> | |
| <!-- ====== THREE THINGS ====== --> | |
| <h2>The Three Things That Actually Work</h2> | |
| <p>Research and user experiences consistently point to three simple changes that make the biggest difference:</p> | |
| <div class="tip-grid"> | |
| <div class="tip-card"> | |
| <h3>1. Eat Protein and Fat Before Carbs</h3> | |
| <p>At every meal, eat your protein first (eggs, meat, cheese, nuts), then vegetables, then carbs last. This dramatically flattens glucose spikes. One user found that adding just one extra egg and a slice of cheese to the same breakfast reduced her spike by 25%.</p> | |
| </div> | |
| <div class="tip-card"> | |
| <h3>2. Walk for 10 Minutes After Eating</h3> | |
| <p>Even a slow stroll makes a huge difference. A pregnant woman found that walking after dessert completely eliminated the spike she expected. You don't need to power walk — gentle movement is enough.</p> | |
| </div> | |
| <div class="tip-card"> | |
| <h3>3. Pair Carbs With Something</h3> | |
| <p>Never eat carbs alone. An apple with peanut butter barely spikes glucose. An apple alone can spike significantly. A waffle eaten before protein? Spike above 150. The same waffle bites after protein? Barely a blip.</p> | |
| </div> | |
| </div> | |

| <!-- ====== WHAT NOT TO DO ====== --> | |
| <h2>What NOT to Do</h2> | |
| <div class="warning-box"> | |
| <ul style="margin-left: 16px;"> | |
| <li><strong>Don't obsess over the numbers.</strong> Post-meal glucose up to 140 mg/dL is normal. A spike means your body is processing food. The goal is patterns, not perfection.</li> | |
| <li><strong>Don't avoid fruit.</strong> Some people see a small spike and stop eating fruit. Fruit is healthy and important during pregnancy.</li> | |
| <li><strong>Don't use this instead of your glucose tolerance test.</strong> Your OB's GD screening at 24-28 weeks is still important.</li> | |
| <li><strong>Don't compare your numbers to non-pregnant people.</strong> Pregnancy changes glucose dynamics — that's normal.</li> | |
| </ul> | |
| </div> | |
| <hr class="divider"> | |
| <!-- ====== WHY NOT THE OTHERS ====== --> | |
| <h2>Why NOT the Others</h2> | |
| <ul> | |
| <li><strong>Nutrisense</strong> has amazing dietitian coaching but <strong>excludes pregnant women</strong> from their program.</li> | |
| <li><strong>Signos</strong> is FDA-cleared for weight loss — its alerts say "Move now!" when your glucose rises. Not what you need when you're exhausted and growing a human.</li> | |
| <li><strong>Abbott Lingo</strong> is $6/month cheaper but doesn't confirm pregnancy safety, has a worse app, is less accurate, and less waterproof.</li> | |
| <li><strong>January AI</strong> builds an AI model of your metabolism, but pregnancy changes your metabolism constantly — a model won't keep up.</li> | |
| <li><strong>Veri</strong> shut down in 2024.</li> | |
| </ul> | |
